The Vedic culture determines the standard of social upliftment in terms of the degree of [Text Missing] self-realization and as such the social division was estimated accordingly in terms of goodness (intelligence and higher learning), passion (martial spirit to lord it over the world), passion-cum-ignorance (the spirit of productivity) and ignorance (the spirit of passive acceptance of being controlled by the laws of material nature).
According to Vedic scriptures the present age is called Kali-yuga and almost all human beings are now degraded to the standard of the mode of ignorance and therefore the greater number of population are subjected to the pangs of the threefold miseries of material existence in the most horrible manner.
In such rabid condition of human being the panacea is "Krishna sankirtana" recommended in all scriptures. By this process, the forgetfulness of human being of his eternal relation with Godhead, is removed altogether.
Sree Chaitanya Mahaprabhu as confirmed incarnation of Sree Krishna the Personality of Godhead inaugurated this sankirtan movement and He reclaimed all conditioned souls from all ranks of life even from animal kingdom for being re-instated in the transcendental relation and activities of loving service to the Absolute Truth. Thakura Haridas who happened to appear in the family of a Mohammedan was one of His principle associates and His transcendental movement embraced all varieties of people beginning from the most erudite scholar brahmanas to the one who came in the family of Javana & Chandala.
