The eighth Mahavidya is Tripurasundari, also known as Kamala. A form of Mahalakshmi, She symbolizes wealth. Her body is golden in color and She is seated on a gold lotus. Here is the story of Her origin.
One day Indra, the ruler of the heavens, saw Rambha and was lost watching her beauty. At that time, the fierce Rishi Durvasa appeared and gave a garland to Indra. But Indra, still mesmerized by Rambha, did not realize what he was doing and gave the garland to his elephant Airavat. Durvasa was angry with the disrespect shown to him and immediately cursed Indra thus, “You are the King of the Gods, but yet you are playing with women. You will lose Lakshmi. She will leave your kingdom.” Goddess Lakshmi, true to the curse, left the heavenly regions.
All the Gods were saddened, and led by Indra went to Vishnu to get His counsel. Vishnu suggested that Lakshmi would appear if they churned the ocean of milk. Both devas and asuras arrived at the ocean of milk (Ksheera samudra). They used Mount Mandara as the central axle and the serpent Anant Nag as a rope to move the mountain. Lord Vishnu took the form a large tortoise to support the Mountain. The asuras and the devas each took the opposite ends of the snake and churned the ocean. As they churned, a lot of beautiful beings and objects manifested including Ucchaisrava (the divine horse), Dhanvantari (the God of Medicine), the Sudharshana Chakra, the Parijata flower. And then came Lakshmi.
When they saw Laksmi, the Gods offered Her an asan with the greatest respect. They did an abishek to Her, offered Her a lotus garland and entreated Her to stay with them, to which She agreed. She became known as Tripurasundari.
Tri means three, Pura means city, and Sundar means beautiful. Tripurasundari is the beautiful one of three cities, or all the threes. She manifests the perfection of compassion in all Nature. To learn Her Bija Mantra and Gayatri please see the Das Mahavidya Presentation
