It was the utmost desire of Sage Viswamitra to defeat his rival Sage Vashishtha. Though he never succeeded ,but he never become dejected. He keep on adding divine powers acquired by him after tapasya. At one time he become so powerful that he started creating many species. This was a threat to Lord Brahma. While Sage Vishwamitra was involved in creation of human species, Lord Brahma rushed towards him to stop. But he already created the head of human. So, the question arises what to do with the created portion. Lord Brahma named that head as “Sriphal” or coconut and blessed that without the sriphal no yagya would be complete. Even today when the covering of coconut is peel off then impression of two human eyes are still visible.
