About Lalita DaviIn Satyug, Prajapati Daksha, father of Sati performed a Yagya known as "Brahaspati-Sak". He didn't called his son-in-law, Lord Shiva. He refused to go to the Yagya and also asked Sati not to go there, but she didn't obeyed him and went to the yagya. There she did not find the share of his husband in the Yagya, angry with this she jumped into the yagya and extinguished herself. On knowing this Lord Shiva lost his temper and started doing "Tandava" by taking the body of Sati on his shoulders. To stop Lord Shiva , Lord Vishnu used his Sudarshan Chakra to cut down the body of Sati into pieces
