The Bhagavata Purana, like other puranas, discusses a wide range of topics including cosmology, astronomy, genealogy, geography, legend, music, dance, yoga and culture. As it begins, the forces of evil have won a war between the benevolent devas (deities) and evil asuras (demons) and now rule the universe. Truth re-emerges as Krishna, (called Hari and Vāsudeva in the text) - first makes peace with the demons, understands them and then creatively defeats them, bringing back hope, justice, freedom and happiness - a cyclic theme that appears in many legends.
