Four Vishnu stories behind Diwali
Rama's return in the north, Narakasura's death in the south and west, Lakshmi's wedding night in Puranic lore, and Bali's return in the Deccan and Gujarat.
In the north the lamps are lit for a homecoming. Rama, having defeated Ravana and finished fourteen years of exile, returns to Ayodhya with Sita, Lakshmana and Hanuman, and the city is said to have lit its streets to welcome the king it had lost. Every row of lamps on Diwali night repeats that welcome.
Puranic tradition ties the festival to Lakshmi: she was born from the churned ocean, and on Diwali night she chose Vishnu and married him, which is why the goddess of fortune is worshipped after dark and the house is lit for her coming.
What is different here:
A wedding rather than a homecoming or a killing; connects the festival to the churning.
In the south and the west the day before Diwali is Naraka Chaturdashi, the anniversary of Krishna's killing of the demon Narakasura; the early bath and the lamps mark the end of his tyranny.
What is different here:
Krishna, not Rama; a victory rather than a return.
On the third day of the festival, Balipratipada, Karnataka, Maharashtra, Gujarat, Telangana and Andhra welcome King Bali back for his yearly day among his people, the same return that Kerala keeps at Onam.
What is different here:
The Vamana story's aftermath rather than Rama or Krishna; kept on the third day.
