Followers of Hinduism believe that Humanscannot afford to lose the blessings of Brahmā and Sarasvati, without whom the populace would lack creativity, knowledge to solve mankind's woes. There is a story of a fifth head. This head came when Shatrupa started flying away from him upwards and the head came on top of the four heads - symbolizing lust and ego. the head was decapitated by Shiva returning Brahmā to his four head avatar which gave birth to the Vedas. The fifth head stayed with Shiva hence Shiva got the name Kapali.
