Nara, in Vedic Hinduism, is a general word for “man,” but in later texts, it came to mean primordial “Man,” the agent through whom the creation of humanity is effected. Nara and Narayanaare also depicted as rsis, the sons of Dharma and Ahimsa, of great ascetic holiness. They are also regarded as emanations of Vishnu, and for that reason the Mahabharata can regard Arjuna and Krishna as emanations of Nara and Narayana.
