After fourteen years in the forest, Rama, Sita and Lakshmana flew home to Ayodhya in the Pushpaka, a flying chariot.
It was a dark night with no moon, so the people lit rows and rows of diyas to show them the way.
The whole city glowed.
On this night, families also pray to Goddess Lakshmi for a happy, lucky year.
Talk about it: How many diyas can you count on the city wall?
