Narasimha is one of the avatars of Lord Vishnu. Other forms of Narasimha include Lakshmi Narasimha, Kevala Narasimha or Vira Narasimha and Ugra Narasimha.
This form, Yoga Narasimha, is in meditation position (Yogasana) with a belt (Yogapatta), supporting legs. This form is seating is also known as Utkutika asana. Lion-faced with mane on the sides, open mouth, with tongue and canine showing is typical of all Narasimha forms. The crown is in the form of a tiara. The rear arms are carrying the attributes of Vishnu, Chakra (wheel) and Shankha (Conch shell). The front arms are resting on his knees in a meditative pose.
Yoga Narashima, because of the ‘restraining’ Yogapatta and Lakshmi Narasimha, as he is accompanied by Shakti, are seen as benign forms of Narasimha.
See the backside view for the design of the mane, necklace, Yajnopavitha (sacred thread), girdle and working of the chakra (discuss).Yogapatta is carried to back as well. No shortcuts here.
Raised lotus petals at the base, deep carving of Shankha and Chakra with holes are some of the indications of the quality of casting/workmanship.
