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.
That which is nearest is least observed. The Atman is the nearest of the near, therefore a careless and unsteady mind gets no clue to the Atman. But one who is alert, calm, self-restrained, and discriminating, ignores the external world and, diving more and more into the inner world, realizes the glory of the Atman and becomes great.
-Swami Vivekananda
