Through His third eye, Lord Shiva is able to see beyond the apparent and destroy all evil.It is believed that first time Lord Shiva had opened his third eye was when he was enraged by the death of his first wife Uma who fell down to the Havan Kund of Daksha Prajapati and she was declared there as Sati.
