In later Hinduism, Nirṛti and Nirṛta is also a male god, who is regarded as a dikapala ("guardian of the directions") of the southwest.
[2][3] This term was used in Vedic texts to indicate a realm of non-existence and absolute darkness, which threatened to consume those who failed in their duties to sacrifice and procreate.
According to some texts, she is the wife of Adharma (not-dharma) that signifies an important component of Prakriti for the Purusha who dwell in forests and the mother of three rakshasas—Mrityu (death), Bhaya (fear) and Mahabhaya (terror)—who were collectively referred to as Nairrita.
[7] Other texts portray her as the daughter of Adharma and Himsa (violence, the opposite of Ahimsa); she married her brother—Arita (not ṛta) and became the mother of Naraka (personification of the hell) and Bhaya.
[16][17] The Vishnudharmottara Purana states that Nirṛti has a terrific appearance with ill-looking eyes, gaping mouth, and exposed teeth.
The Vishnudharmottara Purana also mentions that Nirṛti has four consorts named Devi, Krishnangi, Krishavandana and Krishnapasha.
[16] According to the scripture Devi-Bhagavata Purana, Nirṛti resides in a city named Krishnajana, which is located in the southwestern part of Mount Meru.
