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.
Those who work at a thing heart and soul not only achieve success in it but through their absorption in that they also realize the supreme truth -- Brahman. Those who work at a thing with their whole heart receive help from God.
-Swami Vivekananda
