Sûta said:-- Thus speaking to the Devas, Bhagavatî S’arvânî remained silent. The Devas became very glad and spoke this to Visvakarmâ:-- “Kindly do this Deva work and fix Visnu's head. He will become Hayagrîva and kill the indomitable Dânava.” Sûta said:-- Hearing these words, Visvakarmâ quickly cut off with his axe, the head of a horse, brought it before the Devas and fixed it on the headless body of Visnu. By the grace of Mahâmâyâ, Bhagavân became horse-faced or Hayagrîva. Then, a few days after, Bhagavân. Hayagrîva killed that proud Dânava, the Deva's enemy, by sheer force. Any man, hearing this excellent anecdote, becomes freed, certainly of all sorts of difficulties. Hearing or reading Mahâmâyâ's glorious deeds, pure and sin destroying, gives all sorts of wealth.
Thus ends the fifth chapter of the first Skandha on the description of the narrative of Hayagrîva in the Mahâ Purâna S’rimad Devî Bhâgavatam of 18,000 verses.
