Goddess Padmavati

Goddess Padmavati is the consort of Lord Balaji or Lord Venkateshwara. 

Who is Goddess Padmavathi?
The story of Padmavati is closely associated with the legend of Tirupati. Goddess Lakshmi and Lord Vishnu had a quarrel and Goddess Lakshmi left for earth. Soon Lord Vishnu came in search of her.

Unable to find Goddess Lakshmi, Lord Vishnu built a hermitage in the Venkatadri hill. Here he was looked after by Vakuladevi and was known as Srinivasa.

King Akasha Raja of a nearby kingdom was childless and performed several rituals to get a child. During one such ritual, the king was ploughing a field. Suddenly, the earth cracked and a lotus flower with a baby girl came up. The King named her Padmavati.

(Some legend say that the young girl was granted a boon in her earlier birth that she will marry Lord Vishnu. Another legend says that Padmavati is Goddess Lakshmi.) 

The girl grew up and during one of her expeditions to the forest she met Lord Vishnu. Soon they fell in love. No king would like her daughter to get married to a forest dweller. So there were some initial hiccups, which was resolved by the Lord.

Soon the unparalleled wedding of Srinivasa and Goddess Padmavati took place and they settled in the Venkatadri hill.
