In India, there is a holiday called Diwali. During Diwali, while the children are sleeping, a magical being named Lakshmi visits homes on Diwali, and leaves presents and candies for the children to find when they wake up in the morning.
Lakshmi is the ancient Hindu goddess of prosperity. To find the homes of good Hindu children in India, on the Hindu holiday of Diwali, she follows the light of dipa lamps, placed on window ledges and driveways. While children are sleeping, Lakshmi enters, enjoys the food left for her, and leaves "prosperity" in the form of presents and candies.
In ancient India, and in modern times as well, Dipa lamps are used to grant wishes. Legend says ... to be granted a wish, you must light a dipa lamp and put it in a waterway. If the lamp reaches the other side of the river or creek, your wish will be granted.
