In the Vedas, Pratyangira named as Atharvana Bhadrakali, the ruling goddess of Atharv Veda. She is considered to be a powerful repellent of the influences generated by witchcraft and is said to have the power to punish anyone doing Adharma.
The Shatapatha Brahmana is also considered significant in the development of Vaishnavism as the origin of several Puranic legends and avatars of Vishnu. Notably, all of them (Matsya, Kurma, Varaha, Narasimha, and Vamana) are listed as the first five avatars in the Dashavatara (the ten principal avatars of Vishnu).
Vishnu
Sofia states ''developments that occur in the general character of Visnu in the Brahmana literature have far-reaching influence on the growth and moulding of avataric Visnu... Probably the single most important development, which is first found in the Brahmanas and exerts the most influence over all other factors, is the identification of Vishnu with the sacrifice'.[30] Vishnu is explicitly stated to be sacrifice repeatedly throughout the Shatapatha Brahmana (e.g. SB 1.7.4.20, 1.1.4.9, 3.2.1.38, 3.6.3.3, 5.2.3.6, 5.4.5.1, 5.4.5.18, 11.4.1.4, 12.5.4.11, 14.1.1.13, and 11.4.1.4
puranic mythology
According to many Puranas, at the end of the Krita Yuga, a glittering spark appeared from the universe and transformed into a wicked demon named Vipulasura. Vipulasura disturbed a group of eight sages who were performing rituals of Ashta Lakshmi. This angered the goddess Lakshmi who transformed her holy lotus flower into a kavacha or a strong shield.The shield provided a great protection to the eight sages, and They perform the holy rituals without any disturbance. Then, Laxmi took the form of Narasimhi and defeated and killed the demon Vipulasura.[6]
According to the Markandeya Purana and Shiva Purana, in the beginning of the Treta YugaLord Narasimha the fourth among the ten avataras of Vishnu, full of ugra (rage) against the demon king Hiranyakashipu and kills him by drinking blood after tearing up his body.
But the act of drinking the demon's blood made Lord Narasimha lose his godly attributes and get imbibed with destructive evil attributes. Full of rage and unstoppable, Narasimha was in a destructive mode, and the world was threatened with destruction as he could not be pacified.
The story ends with Prahlada pacifying Narasimha and he returns to Vaikuntha after assuming his true form as Vishnu.[7] In the Shaiva tradition, Shiva assumed the form of Sharabha, a bird-lion hybrid form with two wings of Shakti in the form of Shulini Devi and Pratyangira Devi to calm down Narasimha. Seeing this, Narasimha created Gandaberunda, a powerful two-headed bird, to fight Sharabha. Seeing that the fight between Sharabha and Gandaberunda was terrorizing the world, Pratyangira in her ugra form was released from the third eye of Sharabha. The war ended with Pratyangira's roar. Narasimha so he could resume his Satvik form, and thus Dharma in the world was restored.[
