Narasimha is one of the major deities in Vaishnavism and his legends are revered in Vaikhanasas, Sri Vaishnavism, Sadh Vaishnavism and various other Vaishnavism traditions of Hinduism. The most popular Narasimha mythology is the legend that protects his devotee Prahlada, and creatively destroys Prahlada's demonic father and tyrant Hiranyakashipu. Narasimha is known primarily as the 'Great Protector' who specifically defends and protects his devotees from evil. Vishnu understood the demon's power and creatively adapted into a mixed avatar that is neither man nor animal and kills the demon at the junction of day and night, inside and outside. Endowed with this, he began to create chaos and havoc, persecuting all devotees of Vishnu, including his own son. neither in sky nor on land nor in heaven nor in pataala, by any weapon, and by man, god, asura or animal.

Narasimha iconography shows him with a human torso and lower body, with a lion face and claws, typically with a demon Hiranyakashipu in his lap whom he is in the process of defeating. Alongside, Narasimha is also described as the God of Yoga, in the form of Yoga-Narasimha. There is even a matha (monastery) by the name of Parakala Matha in Sri Vaishnava tradition. Hence he is known as Kala (time) or Mahakala (great-time) or Parakala (beyond time) as well. Narasimha is depicted with three eyes, and is described as the God of Destruction, who destroys the entire universe at the time of great-dissolution ( Mahapralaya). Narasimha, sometimes spelled Narasingha ( / ˈ n ʌr ə ˌ s ɪ ŋ h ə/ Sanskrit: नरसिंह, lit.'man-lion', IAST: Narasiṃha), is a fierce avatar of the Hindu god Vishnu, one who incarnates in the form of part lion and part man to destroy evil and end religious persecution and calamity on Earth, thereby restoring Dharma.
