Maa Lakshmi
The goddess of wealth, prosperity and fortune, worshipped especially during Diwali.
Who Maa Lakshmi is
Lakshmi is the goddess of wealth, prosperity and fortune, and consort of Vishnu. Tradition holds she emerged seated on a lotus during the churning of the cosmic ocean (Samudra Manthan), one of fourteen treasures produced that day — which is why she's also called Padma (lotus-born) and shown seated or standing on one.
Her devotion to Vishnu across his avatars
A distinctive feature of Lakshmi's mythology is that she accompanies Vishnu through his incarnations, taking her own matching form each time: as Sita alongside Rama, and traditionally identified with Rukmini or Radha alongside Krishna. This is read less as mere consorthood and more as continuous, devoted service across every one of his descents to earth.
Symbols
She's typically shown with four arms, holding lotuses and a pot overflowing with gold coins, with coins also flowing from her palm — and flanked by elephants in classical imagery, symbolising royal power and abundance. Her vehicle is sometimes given as an owl.
How she's worshipped
Diwali is her central festival — the cleaning and lighting of homes on Diwali night is meant as a direct invitation for her to enter. The Lakshmi Chalisa and Friday worship (considered her day) are the most common ways devotees seek her blessing through the rest of the year.
