Pleased with his deep devotion, Lord Narasimha (an incarnation of Lord Vishnu) appeared before him in five different forms as Jwala, Yogananda, Gandabherunda, Ugra and Lakshminarasimha.
They later manifested themselves into finely sculpted forms that later came to be worshipped as Panchanarasimha Kshetram. As the legend goes, the Lord appeared first as Jwala Narasimha (Lord as a flame) , when Yadarishi was unable to face the intensity of this apparition, he appeared in a peaceful form as Yoganarasimha (Lord in a Yogic Padmasana posture with open palms on the knees) . Not satisfied with the Lord appearing alone, Yadarishi sought to see him with this consort, so he is said to have appeared with Lakshmi on his lap, known as Lakshmi Narasimha Swamy and as being worshipped by Alwars, his ardent devotees.
