Another tale from the Vishnu Purana tells at the time of the destruction of Daksha's sacrifice (Yajna), Yajna, the lord of sacrifice, was escaping as a deer. Yajna's head was severed by Virabhadra, a fierce incarnation of Shiva. Latter accounts in the Harivamsa and Linga Purana relate this to the origin of the constellation (Nakshatra) Mrigashīrsha (deer-headed). The creator god Brahma elevated the deer-headed Yajna to the planetary sphere as Mrigashīrsha.
