It preached equality. This was in stark contrast to the reality where the society was divided on the lines of religion, caste, gender etc. Ex: Disciples of Ramananda included a weaver, cobbler, barber
It preached universal brotherhood built on values such as love, care, and affection etc for everyone in the society. Ex: Kabir preached universal brotherhood through his Dohas.
It strove hard to rid the religion and society of evil practices that had crept into the society over the years. Ex: Guru Nanakcondemned caste difference and rituals like bathing in holy rivers. His idea of religion was highly practical and strictly moral.
Perhaps the most important aspect of the movement was its emphasis on the route of ‘Bhakthi’ rather than superficial rituals as the mode to realize god and salvation.
