Lives and philosophies, as well as spiritual practices advocated by the founders of the major Vaishnava philosophical schools: Ramanuja, Nimbarka, Madhva, Vallabha, and Chaitanya.
Anything that is secret and mysterious in these systems of yoga should be at once rejected. The best guide in life is strength. In religion, as in all other matters, discard everything that weakens you, have nothing to do with it.
-Swami Vivekananda
