According to Nanditha Krishna, a simpler form of this legend, one without Mahabali, is found in the Rigveda and the Vedic text Shatapatha Brahmana where a solar deity is described with powers of Vishnu. This story likely grew over time, and is in part allegorical, where Bali is a metaphor for thanksgiving offering after a bounty of rice harvest during monsoon, and Vishnu is the metaphor of the Kerala sun and summer that precedes the Onam. According to Roshen Dalal, the story of Mahabali is important to Onam in Kerala, but similar Mahabali legends are significant in the region of Balia in Uttar Pradesh, Bawan also in the same state, Bharuch in Gujarat, and Mahabaleshwar in Maharashtra. The story is significant not because Mahabali's rule ended, but it emphasizes the Hindu belief in cyclical nature of events, that no individual, no ruler and nothing lasts forever, except the virtues and self understanding that overcomes all sorrow.
