As a result, he humiliated Lord Shiva and Sati at a religious occasion in his house. She could not take it and jumped into the fire of Yajna. Later, she took birth in the home of Parvat Raj Himalaya the King of the Himalayas as Parvati (hence she got the name Shailputri and Hemavati) and married Lord Shiva again. As she rides on the bull, she is also known as Vrisharudha (Vrisha = bull and Arudha = to be placed upon). She is also known as Bhavani.
