A story associated with Goddess Lakshmi and an old lady explains the importance of performing Lakshmi puja on Diwali. This Diwali Lakshmi puja katha narrates the significance of lightning Diya (lamp) on Diwali night.
One day Goddess Lakshmi was roaming on earth. It was the Kartik Amavasya day – no moon day in Kartik month. She roamed and forgot about night approaching. Because of the darkness created by no moon day, Goddess Lakshmi lost her way and decided to stay among humans on the day.
But when Goddess Lakshmi looked around she found that all the houses were closed and there were no Diya (light) burning.
After roaming for a while she came across a home which in which a Diya was burning. It was a dilapidated hut of an old woman.
When Goddess Lakshmi reached the hut, the old woman invited her into the home and said that it was not safe for a maiden to roam around on a dark night.
She offered the little food that was in her home and made bed for Goddess Lakshmi.
The next day morning when the old woman woke up she found that the maiden had gone.
To her surprise, the old woman found that her dilapidated hut had become a palace and she found gold and diamond scattered all around.
