Before Diwali night, people clean, renovate and decorate their homes and offices. On Diwali night, Hindus dress up in new clothes or their best outfits, light up diyas (lamps and candles) inside and outside their home, and participate in family "puja" (prayers) typically to Lakshmi. After "puja", fireworks follow, then a family feast including "mithai" (sweets), and an exchange of gifts between family members and close friends. Diwali also marks a major shopping period, since Lakshmi connotes auspiciousness, wealth and prosperity. This festival dedicated to Lakshmi is considered by Hindus to be one of the most important and joyous festivals of the year.
