Lakshmi Puja is a main ritual observed on Diwali (Deepavali). According to Puranas and other Hindu Sacred texts, diya or deepam marks the presence of Lakshmi in that particular place.
Goddess Lakshmi is emerged to take away the darkness around us. There are some special stotras or prayers to praise and please Goddess Lakshmi.
Here is one of the Diwali Lakshmi stotras:
