Lives and philosophies, as well as spiritual practices advocated by the founders of the major Vaishnava philosophical schools: Ramanuja, Nimbarka, Madhva, Vallabha, and Chaitanya.
Let each one of us pray day and night for the downtrodden millions, who are held fast by poverty, priestcraft, and tyranny. Pray day and night for them. I care more to preach religion to them than to the high and the rich. I am no metaphysician, no philosopher, nay, no saint. But I am poor and I love the poor.
-Swami Vivekananda
