What is the significance of Rangoli on Diwali?

Rangoli is a sacred ritual to welcome Goddess Lakshmi into the home and ward off negative energies during Diwali. Intricate footprint symbols and lotus motifs guide her blessings into the home and keep evil spirits at bay. Rangoli also expresses warm hospitality. Traditionally, it's made with rice flour, which serves as food for ants, birds and small insects.
