Bhagavata is best described in its own words: rasa. It means "nectar." Nectar here denotes "a kind of joy" which one derives by coming into contact with God in and through his divine sports.
I am the thread that runs through all these pearls, and each pearl is a religion or even a sect thereof. Such are the different pearls, and God is the thread that runs through all of them; most people, however, are entirely unconscious of it.
-Swami Vivekananda
