“I bow down to Lord Nrisimha who is ferocious and heroic like Lord Vishnu. He is burning from every side. He is terrific, auspicious and the death of death personified.”
This mantra is quoted or at least referred to in many scriptures. The Nrisimha Tapani Upanishad also gives the history of this mantra. In the last creation the presiding deity was Lord Nrisimhadeva and this was the mantra inspiring the entire creation into which Lord Brahma was initiated, as in the present creation the presiding deity is Shri Krishna and He initiated Brahma into the Kama-Gayatri.
In Jagannatha Puri the pujaris believe that Lord Jagannatha is from the previous creation and was originally worshipped as Lord Nrisimhadeva. Jagannatha Puri Dhama floats on the ocean of devastation and is thus never destroyed. Every twelve or nineteen years the Deities' forms are changed. The installation yajna for the new Deities takes about two weeks and is mainly comprised of a Nrisimha mantrawhich is chanted 20,000 times.
