Introduction
The Industrial Revolution saw a rapid development of industry take place in Britain in the late 18th and early 19th centuries, soon spreading to Western Europe and North America. New and improved large-scale production methods and machinery marked the beginnings of Industrialization. Many different factors contributed to the rise of the Industrial Revolution in Britain and paved the way for Britain to become an industry-driven country.
Body
Impacts of Industrialization
Positives:
- The Industrial Revolution brought about sweeping changes in economic and social organization.
- These changes included a wider distribution of wealth and increased international trade.
- Managerial hierarchies also developed to oversee the division of labor.
- By the late 1700s many people could no longer earn their living in the countryside. Increasingly, people moved from farms and villages into bigger towns and cities to find work in factories.
- The Industrial Revolution marked a dramatic change for women as many of them entered the workforce for the first time. Women had to compete with men for jobs. Female factory workers often made only one-third as much as men.
- Machines greatly increased production. This meant that products were cheaper to make and also cheaper to buy. Many factory owners became rich.
- The middle class began opening up new factories for which they required financing and therefore, the banking and finance system began developing.
- Better transport, communications and mechanized goods made life comfortable for man.
Negatives:
- Advancement in technology and better agricultural production led to better medical facilities and greater employment which led to population explosion.
- Although the machines made work easier in some ways, factory work created many problems for the laborers. Factory employees did not earn much, and the work was often dangerous. Many worked 14 to 16 hours per day six days per week.
- Women and child labour was badly exploited.
- Workers sought to win improved conditions and wages through labor unions. These organizations helped establish laws to protect workers. Such laws, for instance, limited the number of work hours for employees and guaranteed they would be paid a certain amount.
- Cities grew larger, but they were often dirty, crowded, and unhealthy.
- Industrial Revolution made the production of goods easy and ready in much less time. Therefore, more and more goods began to be produced which led to the exploitation of resources.
- The process of industrialization continues around the world, as do struggles against many of its negative effects, such as industrial pollution and urban crowding.
- It led to wars of imperialism and colonization.
Impact of Industrial revolution on India:
- The Industrial Revolution in England impacted the nature of trade of the British in India.
- The Industrial Revolution transformed India into a country that supplied raw-materials to the industrial houses of Britain.
- Prior to the Industrial Revolution British traders purchased cotton piece- goods and other handicraft items from India and used to net huge profit by selling those in the European markets.
- With the Industrial Revolution Britain started manufacturing various articles in a short time. For the manufacture of such articles huge raw-materials were needed.
- Thus they procured raw-materials from India at a cheap price.
- At the same time Britain flooded the Indian markets with the machine-made products produced in British factories.
Conclusion
Industrialization changed our world for the better in many ways. It is up to us to clean up the pollution that comes about as a side effect to these efforts. If we’re unwilling to approach our environment in the same way that we look at our economies, then this planet we have may not be around much longer.

Introduction
Solid waste management (SWM) refers to the process of collecting and treating solid wastes. It also offers solutions for recycling items that do not belong to garbage or trash. In a nascent effort to look beyond toilets and kick off its ODF+ phase — that is, Open Defecation Free Plus — focussing on solid and liquid waste management, the Swachh Bharat Abhiyan (SBA) has included the prevalence of plastic litter and water-logging in villages as indicators of cleanliness in its 2019 rural survey.
Body
Current Situation of SWM in India:
- The March 2 fire at Brahmapuram was not the first at the waste processing plant — a euphemism for a sprawling 110-acre open dumping yard with a failed windrow composting facility and a yet-to-begin waste-to-energy plant. The yard has been witnessing fire outbreaks at almost the same time every year in the last few years. The Kochi Municipal Corporation, which runs the plant, initially provided a typically listless response. But this proved calamitous as the blaze raged on and a blanket of fetid smoke soon shrouded the city and nearby areas.
- As per the SBM 2.0 guidelines, the total quantity of waste generated by urban areas in India is about 32 lakh tonnes daily. This adds up to 8 crore tonnes per annum.
- Of this only about 25% is being processed; the rest is disposed of in landfills every year.
- Given that the waste dumpsites have been operational since the early 2000s, more than 72 crore tonnes of waste need to be processed.
- Most cities have confined themselves to collection and transportation of solid waste. Processing and safe disposal are being attempted only in a few cases.
- The CPCB report also reveals that only 68% of the MSW generatedin the country is collected of which, 28% is treated by the municipal authorities. Thus, merely 19% of the total waste generated is currently treated.
- According to a UN report, India’s e-wastefrom old computers alone will jump 500 per cent by 2020, compared to 2007.
- Disappearance of urban water bodies and wetlands in urban areas can be attributed to illegal dumping of Construction & Demolition waste.
Some of the major issues concerning solid waste management are:
- Absence of segregation of waste at source.
- Lack of funds for waste management at ULBs.
- Unwillingness of ULBs to introduce proper collection, segregation, transportation and treatment/ disposal systems.
- Lack of technical expertise and appropriate institutional arrangement
- Lack of infrastructure and technology
- Lack of involvement from the private sector and non-governmental organisations
- Indifference of citizens towards waste management due to lack of awareness
- Lack of community participation towards waste management and hygienic conditions
- Lack of sewage management plan.
- About 70% of the plastic packaging products turn into plastic waste within a short period.
- Unorganized vendors and markets, existence of slum areas and Corruption are other issues plaguing MSWM.
Measures needed
- State governments should provide financial support to ULBs to improve their waste management system under various schemes and programs.
- Initiatives like Smart Cities Mission, AMRUT should provide significant funding to improve civic services infrastructure.
- The key to efficient waste management is to ensure proper segregation of waste at source and to ensure that the waste goes through different streams of recycling and resource recovery as stated in the Solid Waste Management Rules, 2016.
- Waste to energy is a key component of SWM. Installation of waste-to-compost and bio-methanation plants would reduce the load of landfill sites
- There is a need to encourage research and development so as to reinvent waste management system in India.
- The focus should be on recycling and recovering from waste and not landfill. Further, it is important to encourage recycling of e-waste so that the problem of e-waste
- Public- Private Partnership models for waste management should be encouraged.
- Construction and demolition waste should be stored, separately disposed off, as per the Construction and Demolition Waste Management Rules, 2016.
- Responsibilities of Generators have been introduced to segregate waste in to three streams, Wet (Biodegradable), Dry (Plastic, Paper, metal, wood, etc.) and domestic hazardous wastes (diapers, napkins, empty containers of cleaning agents, mosquito repellents, etc.) and handover segregated wastes to authorized rag-pickers or waste collectors or local bodies.
- Sensitization of citizens as well as government authorities, community participation, involvement of NGOs. Littering should be prohibited.
- International Best practices should be emulated. South Korea is one of the few countries to separate and recycle food waste. It has also launched landfill recovery projects such as the Nanjido recovery project which have successfully transformed hazardous waste sites into sustainable ecological attractions.
Conclusion
Municipal solid waste management (MSWM) is one of the major environmental problems of Indian cities. The need of the hour is scientific, sustainable and environment friendly management of wastes.

Why the question:
The article discusses the concept of Universal Health Coverage (UHC) and the need for a newer, more comprehensive version of UHC that can address the challenges faced by healthcare systems in the 21st century.
Key Demand of the question:
To write about UHC, challenges in its implementation and steps that are needed to overcome them.
Directive word:
Evaluate – When you are asked to evaluate, you have to pass a sound judgement about the truth of the given statement in the question or the topic based on evidence. You must appraise the worth of the statement in question. There is scope for forming an opinion here.
Structure of the answer:
Introduction:
Begin by defining Universal Health Coverage (UHC)
Body:
In the first part, write about the various components of UHC – access to health services, including preventive, curative, rehabilitative, and palliative care.
Next, write about challenges in the implementation of UHC – funding, human resources, infrastructure, and political will etc.
Next, write about the steps that are needed to overcome the above-mentioned challenges.
Conclusion:
Conclude by writing a way forward.
Introduction
Universal health coverage (UHC) means that all people have access to the health services they need (prevention, promotion, treatment, rehabilitation and palliative care) without the risk of financial hardship when paying for them.
Health accessibility and affordability remain a crucial healthcare problem even in the 21st century. Therefore, World Health Organisation chose “Universal Health Coverage” as the theme for World Health Day 2019. India started working towards the universal problem of affordability and accessibility with the introduction of Ayushman Bharat.
Body:
Significance of UHC:
- Universal health coverage has a direct impact on a population’s health and welfare.
- Access and use of health services enables people to be more productive and active contributors to their families and communities.
- It also ensures that children can go to school and learn.
- At the same time, financial risk protection prevents people from being pushed into poverty when they have to pay for health services out of their own pockets.
- Universal health coverage is thus a critical component of sustainable development and poverty reduction, and a key element of any effort to reduce social inequities.
- Universal coverage is the hallmark of a government’s commitment to improve the wellbeing of all its citizens.
Issues and Challenges:
- Finance: At about 1.3% of the national income, India’s public healthcare spending between 2008 and 2015, has virtually remained stagnant. This is way less than the global average of 6 per cent. It is a herculean task to implement a scheme that could potentially cost Rs 5 lakh per person and benefit 53.7 crore out of India’s 121 crore citizenry, or roughly about 44% of the country’s population. Over 70 per cent of the total healthcare expenditure is accounted for by the private sector.
- Crumbling public health infrastructure: Given the country’s crumbling public healthcare infrastructure, most patients are forced to go to private clinics and hospitals. There is a shortage of PHCs (22%) and sub-health centres (20%), while only 7% sub-health centres and 12% primary health centres meet Indian Public Health Standards (IPHS) norms.
- High Out of Pocket Expenditure: Reports suggest that 70% of the medical spending is from the patient’s pockets leading to huge burden and pushing many into poverty. Most consumers complain of rising costs. Hundred days into the PMJAY, it remains to be seen if private hospitals provide knee replacement at Rs 80,000 (current charges Rs 3.5 lakh) bypass surgery at Rs 1.7 lakh (against Rs 4 lakh).
- Insurance: India has one of the lowest per capita healthcare expenditures in the world. Government contribution to insurance stands at roughly 32 percent, as opposed to 83.5 percent in the UK. The high out-of-pocket expenses in India stem from the fact that 76 percent of Indians do not have health insurance.
- Doctor-Density Ratio: The WHO reports the doctor-density ratio in India at 8 per 10,000 people as against one doctor for a population of 1,000. To achieve such access, merely increasing the number of primary and secondary healthcare centres is not enough.
- Shortage of Medical Personnel: Data by IndiaSpend show that there is a staggering shortage of medical and paramedical staff at all levels of care: 10,907 auxiliary nurse midwives and 3,673 doctors are needed at sub-health and primary health centres, while for community health centres the figure is 18,422 specialists.
- Rural-urban disparity: The rural healthcare infrastructure is three-tiered and includes a sub-center, primary health centre (PHC) and CHC. PHCs are short of more than 3,000 doctors, with the shortage up by 200 per cent over the last 10 years to 27,421. Private hospitals don’t have adequate presence in Tier-2 and Tier-3 cities and there is a trend towards super specialisation in Tier-1 cities.
- Social Inequality: The growth of health facilities has been highly imbalanced in India. Rural, hilly and remote areas of the country are under served while in urban areas and cities, health facility is well developed. The SC/ST and the poor people are far away from modern health service.
- Poor healthcare ranking: India ranks as low as 145th among 195 countries in healthcare quality and accessibility, behind even Bangladesh and Sri Lanka.
- Commercial motive: lack of transparency and unethical practices in the private sector.
- Lack of level playing field between the public and private hospitals: This has been a major concern as public hospitals would continue receiving budgetary support. This would dissuade the private players from actively participating in the scheme.
- Scheme flaws: The overall situation with the National Health Mission, India’s flagship programme in primary health care, continues to be dismal. The NHM’s share in the health budget fell from 73% in 2006 to 50% in 2019 in the absence of uniform and substantial increases in health spending by States.
Steps taken up currently:
- The National Health Policy (NHP) 2017 advocated allocating resources of up to two-thirds or more to primary care as it enunciated the goal of achieving “the highest possible level of good health and well-being, through a preventive and promotive healthcare orientation”.
- A 167% increase in allocation this year for the Pradhan Mantri Jan Arogya Yojana (PMJAY) — the insurance programme which aims to cover 10 crore poor families for hospitalisation expenses of up to ₹5 lakh per family per annum.
- The government’s recent steps to incentivise the private sector to open hospitals in Tier II and Tier III cities.
- Individual states are adopting technology to support health-insurance schemes. For instance, Remedinet Technology (India’s first completely electronic cashless health insurance claims processing network) has been signed on as the technology partner for the Karnataka Government’s recently announced cashless health insurance schemes.
Measures needed to strengthen the existing state of Health infrastructure in the country are:
- There is an immediate need to increase the public spending to 2.5% of GDP, despite that being lower than global average of 5.4%.
- The achievement of a distress-free and comprehensive wellness system for all hinges on the performance of health and wellness centres as they will be instrumental in reducing the greater burden of out-of-pocket expenditure on health.
- there is a need to depart from the current trend of erratic and insufficient increases in health spending and make substantial and sustained investments in public health over the next decade.
- A National Health Regulatory and Development Framework needs to be made for improving the quality (for example registration of health practitioners), performance, equity, efficacy and accountability of healthcare delivery across the country.
- Increase the Public-Private Partnerships to increase the last-mile reach of healthcare.
- Generic drugs and Jan Aushadi Kendras should be increased to make medicines affordable and reduce the major component of Out of Pocket Expenditure.
- The government’s National Innovation Council, which is mandated to provide a platform for collaboration amongst healthcare domain experts, stakeholders and key participants, should encourage a culture of innovation in India and help develop policy on innovations that will focus on an Indian model for inclusive growth.
- India should take cue from other developing countries like Thailand to work towards providing Universal Health Coverage. UHC includes three components: Population coverage, disease coverage and cost coverage.
- Leveraging the benefits of Information Technology like computer and mobile-phone based e-health and m-health initiatives to improve quality of healthcare service delivery. Start-ups are investing in healthcare sector from process automation to diagnostics to low-cost innovations. Policy and regulatory support should be provided to make healthcare accessible and affordable.
Way forward:
- For UHC to become a reality, it is important to expedite steps beyond infrastructural interventions to include water, sanitation, nutrition and a healthy lifestyle. The challenge is to incentivize wellness-seeking behaviour.
- An encouraging aspect of India’s commitment to UHC has been the active and participatory role of the government.
- From Poshan Abhiyaan, which aims to eliminate the malaise of malnutrition, to the Prime Minister’s call for a Fit India Movement, new emphasis has been given to multi-stakeholder engagements.
- India has to align the vision of medical education with the vision of “one nation, one healthcare sector”.
- The National Medical Commission (NMC) 2019 Bill recognizes the much-needed reforms in medical education.
- The challenge of building capacity of people in a short time needs to be addressed through more transformational public-private partnerships (PPPs), presenting another opportunity to develop and adopt e-learning models.
- Digital health has emerged as a game-changer in achieving UHC goals. India has taken rapid strides here and digital health is bringing healthcare within reach of 70% of our population residing in rural and remote areas.
- With the use of digital technology, India is positioned to not only bridge gaps in our healthcare delivery but also to have the capability to contribute to global UHC goals through its telemedicine and digital health tools.
- India’s healthcare providers are already working on new frontiers of digital technologies.
- Machine learning, blockchain and AI will continue to strengthen India’s ability to engage effectively with other geographies towards achieving global UHC targets.
- Regional disparities in terms of resources and institutional capabilities must be addressed. This diversity, nevertheless, can be a powerful source of policy innovation and creativity.
- A collaborative approach aligning patients, payers and providers, along with innovative partnerships, will hasten efforts to mitigate risks, drive impact, forge stronger social returns and achieve sustainable UHC targets.
Conclusion:
India needs a holistic approach to tackle problems in healthcare industry. This includes the active collaboration of all stakeholders’ public, private sectors, and individuals. Amore dynamic and pro-active approach is needed to handle the dual disease burden. A universal access to health makes the nation fit and healthy, aiding better to achieve the demographic dividend.

Introduction
Stagflation, as defined by Princeton economist Alan S. Blinder, is “the simultaneous occurrence of economic stagnation and comparatively high rates of inflation”. Stagflation is an economic condition that’s caused by a combination of slow economic growth, high unemployment, and rising prices. It is said to happen when an economy faces stagnant growth as well as persistently high inflation.
The latest global financial developments and recent economic data in India are together raising fears that several major economies worldwide, including India’s, may be headed for a spell of debilitating stagflation.
Body
Vulnerability of India to stagflation
- Like all emerging markets that rely upon the rest of the world for commodities and capital, India has spent the last two years battling the twin challenges posed by more expensive raw materials and a stronger dollar.
- The expansion in gross domestic product slowed to 4.4% in the December quarter in 2022 with private consumption increasing by just 2.1% from a year earlier, down from 8.8% in the previous three months. Such a sharp deceleration in spending around major Hindu festivals is worrying.
- With investments also starting to slow from the high growth witnessed earlier during this fiscal year, the outlook for domestic demand has turned weak.
- Financial conditions are tight almost across the globe, and demand tepid.
- There’s no end in sight to Russia’s war in Ukraine. Even China, emerging from its long isolation, has set a modest annual growth target of around 5% , though the one positive side-effect of that may be that commodity prices won’t run away again.
- The Federal Reserve is far from declaring victory on inflation, and some European economies, such as Germany and Italy, are forecast to tip into recession.
- Tremors in other emerging markets are also causing a ripple effect, with a highly disruptive currency ban in Nigeria contributing to likely production cuts at Bajaj Auto Ltd.’s Indian factories.
- Export volumes at the motorcycle maker hit a 30-month low in January.
- Nomura Holdings Inc. is predicting that GDP in the world’s fifth-biggest economy will expand 5.3% in the financial year that starts on April 1, way below the central bank’s 6.4% forecast.
- Borrowing costs have risen to a point where higher mortgage payments could be affecting household budgets.
- Overall, India’s growth drivers are slowly fizzling.
Measures needed to tackle stagflation
- A strong monetary policy support for a sustained and inclusive recovery is the need of the hour.
- The focus should be to normalise the prudential policies and the strengthen the insolvency frameworks and restructure mechanisms, including for the overhang of public and private debt.
- There is a need to increase aggregate supply through supply-side policies, for example, privatisation and deregulation to increase efficiency and reduce costs of production.
- Private sector must be incentivised to invest more and to increase supply through tax measures.
- Higher liquidity and disposable income, and increased employment can pull us out of the quagmire.
- reduction and reform of direct individual and corporate taxes, and indirect taxes.
- Frictions in the labour market should be reduced by reducing the time and cost involved in obtaining information about employment opportunities.
- Barriers which either limit entry into a profession or maintain wages at artificially high rates should be removed.
- The government needs to hold granular conversations with the private sector.
- A skills and industrial policy which can make full use of an abundant pool of reasonably priced labour
Conclusion
There is a need to control Stagflation at the earliest by arresting inflation through policy and structural means. Meanwhile, the government should engage all stakeholders to address the supply-side issues, a calming down of food prices will help the government to prevent stagflation in the economy.
Value addition
Stagflation:
- Stagflation is a portmanteau of stagnant growth and rising inflation.
- Typically, inflation rises when the economy is growing fast.
- That’s because people are earning more and more money and are capable of paying higher prices for the same quantity of goods.
- When the economy stalls, inflation tends to dip as well – again because there is less money now chasing the same quantity of goods.
- Stagflation is said to happen when an economy faces stagnant growth as well as persistently high inflation.
- That’s because with stalled economic growth, unemployment tends to rise and existing incomes do not rise fast enough and yet, people have to contend with rising inflation.
- So people find themselves pressurised from both sides as their purchasing power is reduced.

Introduction
Ecology is the study of the relationships between living organisms, including humans, and their physical environment; it seeks to understand the vital connections between plants and animals and the world around them.
Also, Ecology also provides information about the benefits of ecosystems and how we can use Earth’s resources in ways that leave the environment healthy for future generations.
Body
Principles of ecology
- Evolution organizes ecological systems into hierarchies.
- Individual organisms combine into populations, populations combine into species, species combine into higher taxa like genera and phyla.
- Each can be characterized by its abundance and diversity (number of kinds) in a given ecosystem or study plot.
- How and why abundance and diversity vary in time and space is the basic question of ecology.
- The sun is the ultimate source of energy for most ecosystems.
- Life runs on the carbon-rich sugars produced by photosynthesis; every ecosystem’s sugar output depends on how much solar energy and precipitation it receives.
- Organisms are chemical machines that run on energy.
- The laws of chemistry and physics limit the ways each organism makes a living and provide a basic framework for ecology.
- The supply of chemical elements and the sugars needed to fuel their assembly into organisms limit the abundance and diversity of life.
- Chemical nutrients cycle repeatedly while energy flows through an ecosystem.
- The atoms of elements like C, N, P, and Na go back and forth from spending time in living to spending time in dead parts of an ecosystem.
- But the photons of solar energy can be used only once before they are lost to the universe.
- dN/dt=B-X+I
- The rate that a population’s abundance in a given area increases or decreases reflects the balance of its births, deaths, and net migration into the area.
- Individuals with features that improve their ability to survive (i.e., not die) and make copies of themselves will tend to increase in that population.
- dS/dt=D-X+I
- The rate that the diversity of species in an area changes reflects the balance of the number of new forms that arise, those that go extinct, and those that migrate into the area.
- Individuals and species that have features allowing them to survive and reproduce in a local environment will tend to persist there.
- Organisms interact—do things to each other—in ways that influence their abundance.
- Individual organisms can eat one another, compete for shared resources, and help each other survive.
- Each pair of species in an ecosystem can be characterized by the kind and strength of these interactions, measured as their contribution to dN/dt.
- Ecosystems are organized into webs of interactions.
- The abundance of a population is influenced by the chains of interactions that connect it to the other species in its ecosystem.
- This often leads to complex behavior, and a key challenge in ecology is to determine what patterns of abundance and diversity can be predicted.
- Human populations have an outsized role in competing with, preying upon, and helping other organisms.
- Humans are one of millions of species embedded in Earth’s ecosystems.
- The ability of humans to change the planet, abetted by our large population size and technological prowess, increases our ability to shape the biosphere’s future.
- Humans, through principles 1-8, are currently changing the climate, re-arranging its chemistry, decreasing populations of food, moving around its species, and decreasing its diversity.
- Ecosystems provide essential services to human populations.
- These include products like timber, fiber and food, regulating water and air quality, and cultural benefits like recreation.
- A key goal of ecology is to use principles 1-9 to preserve ecosystem services.
Importance of these ecological principles
Conclusion
The Ecology is maintained by smooth interaction between organisms and the environment around it. Any unwarranted action in either of the sides can lead to ecological imbalances resulting in calamities and disruption.

Introduction
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.
Due to the increasing levels of pollution, there is a transfer of chemicals and pollutants as well along with the nutrients leading to accumulation & concentration at different trophic levels.
Body
Biomagnification (Bioamplification) is the process by which chemical contaminant are concentrated at levels that exceed chemical equilibrium from dietary absorption of the chemical. It refers to an increase in the concentration of a substance as you move up the food chain. This often occurs because the pollutant is persistent, meaning that it cannot be, or is very slowly, broken down by natural processes. These persistent pollutants are transferred up the food chain faster than they are broken down or excreted.
In contrast, bioaccumulation occurs within an organism, where a concentration of a substance builds up in the tissues and is absorbed faster than it is removed. Through the food chain, chemicals like PCBs, DDT, dioxins, and mercury build up in the bodies of organism.
Bioaccumulation often occurs in two ways, simultaneously: by eating contaminated food, and by absorption directly from water. This second case is specifically referred to as bioconcentration.
Bioconcentration is the intake of chemical contaminants through an organism’s epithelial tissues or gills, and the subsequent concentration of that chemical contaminant within the organism’s tissues to a level that exceeds ambient environmental concentrations.
Bioconcentration and bioaccumulation happen within an organism, but biomagnification occurs across levels of the food chain.
An example: phytoplankton and other microscopic organisms take up methylmercury and then retain it in their tissues. Here, mercury bioaccumulation is occurring: mercury concentrations are higher in the organisms than it is in the surrounding environment. As animals eat these smaller organisms, they receive their prey’s mercury burden. Because of this, animals that are higher in the food chain have higher levels of mercury than they would have due to regular exposure. With increasing trophic level, mercury levels are amplified.
Conclusion
The need of the hour is to prevent biomagnification or biological magnification by reducing agricultural runoff, restricting use of some heavy metals like lead, mercury and harmful compounds like DDT.

Major aspects of Swami Vivekananda’s ethical philosophy
- Tolerance: Swami Vivekananda preached tolerance and peace for humankind. His idea of peace and tolerance was global and included people of all the religions and sects. If humans are to thrive and prosper, they need to tolerate the diversified views and strive for the prosperity of all.
- Right Education: He stressed that good education is not merely learning of facts but also development of character. He redefined the concept of education which was not limited to exploring means of earning only. For him education was way to build one’s character, strength, intellect etc. Such idea of education would help in evolving oneself as better person in both personal and public life.
- Strength: Swami Vivekananda stresses on the importance of being strong in the life. Weakness comes with number of difficulties for one in a life. Whether its personal goals or professional goals, a person need to be fearless and firm to achieve them.
- Religion: He argued in favour of religious reforms. He stressed that rationality must be applied to root out evils in religion. His meaning of religion had no place for superstitions, unending rituals and practices and religion that was adrift of spiritual content. His idea of religion was humane, did not have necessity of middlemen to connect with one’s god and did not have barriers of caste, community etc. Such progressive understanding of the religion would relieve people from wrong notions of religion and provide them with real spiritual upliftment.
- Fraternity: Swami Vivekananda focuses on the values like Love, Patience, and Perseverance in one’s life. This would increase the brotherhood and fraternity among the people, reduce conflicts among them and would bind the society as a whole.
- Self-faith: Having faith on oneself is the most important. In order to live a good life, people make all sorts of efforts, but they forget to trust themselves, lack confidence and depend on supernatural powers to help them out of their miseries.
Importance of compassion as per Swami Vivekananda
- Compassion is the feeling of oneness with others.
- It is not just showing sympathy and empathy towards others. In the words of the Gita, real compassion is ‘sarva-bhūtastham ātmānaṁ; seeing the Self in all beings’ or ‘sarva-bhūtāni chātmani; seeing all beings in the Self.
- He stressed that success at the cost of poor is not worth having.
- He tells us that as a part of society every person is responsible for the welfare of poor and marginalised people.
- It emphasizes the need to have empathy and compassion for the weaker sections of the society.
Conclusion
It is high time for the youth to come forward by shedding their fears to shape up India. Swamiji laid great stress on Vasudev Kutumbakam. He argued that instead of differences if we focused on the similarities we all share then this world would be a happier place. His teachings are relevant today since many problems remained the same. His teachings reflects a path to these problems.

A small anecdote on Swami Vivekananda’s compassion
Swami Vivekananda was staying in the Math. Some Santhal laborers used to work in the Math. They were poor, uneducated and simple. Swamiji had great sympathy, bordering on love, for these laborers who, despite honest and hard labor, could not feed their family adequately. The compassionate heart of Swami Vivekananda would grieve and melt for these poor fellows. He would inquire about their family, say simple jokes, and mix with these ‘lowly fellows’. The spiritual personality of Swamiji would see suffering Narayana in them. His heart would get filled with unparalleled pity, compassion, and kindness towards these Santhal workers.
Like Gopis of Vraja, who would protest to Krishna not to play the sweet music on his flute, for it attracted them to Him and His Raas Lila with such great intensity that they used to forget their homes and husbands, these workers would also protest: “O my Swamiji, do not come to us when we are working, for while talking to you our work stops and the supervising swami rebukes us afterwards.” With such intensity of love, Swami Vivekananda would attract these poor laborers.
One day Swamiji had a desire to feed these workers. Accordingly, he made arrangements for their lunch. At his orders, bread, curry, sweets, and curds etc. were arranged for the Santhals. Sitting before the Swami, all of them relished the sumptuous food. One Keshta said: “O Swami, whence have you got such a thing! We never tasted anything like this.” Feeding them to their heart’s content, Swami Vivekananda said, “You are Narayana, God manifest; today I have offered food to Narayana.”
Turning to the disciple, the Swami said: “I found them the veritable embodiment of God – such simplicity, such sincere guileless love I have seen nowhere else.” And later addressing the sannyasins of the Math, Swami Vivekananda had said: “Can you mitigate their misery a little! Otherwise, of what good is the wearing of the Gerrua (ochre) robe? Sacrifice of everything for the good of others is real sannyasa…” “Seeing the poor people of our country starving for food, a desire comes to my mind to overthrow all ceremonial worship and learning, and go around from place to place to serve these poor and afflicted…”
