Diwali is primarily associated with Lakshmi Puja, the worship of Goddess Lakshmi, who symbolizes wealth and prosperity. The main Diwali day is called Lakshmi Puja in many regions, and devotees light lamps and pray for prosperity. While Ganesh is often worshipped alongside Lakshmi, the festival is not primarily associated with Ganesh Puja, Kartik Puja, or Durga Puja.
