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.
Change is always subjective. To talk of evil and misery is nonsense, because they do not exist outside. If I am immune from all anger, I never feel angry. If am immune from all hatred, I never feel hatred.
-Swami Vivekananda
