leader, monk, and philosopher of the Indian religion Jainism and the recognized founder of one of Jainism's two principal sects, Digambara.

According to Digambara tradition, in 310 BCE, after a 12-year famine, Bhadrabahu and Candra Gupta (Chandra Gupta)—the first king of the Mauryan (Mauryan empire) dynasty, who had become a Jain monk—led an exodus from the Jain stronghold in northern India. This migration, to Shravana Belgola in what is now the state of Karnataka in southwestern India, was the beginning of the schism in the Jain community between the Digambara (“Sky-clad,” i.e., naked) and Shvetambara (Śvetāmbara) (“White-robed”) sects.

Bhadrabahu is recognized as the founder of the Digambara sect. He also reputedly authored three of Jainism's sacred books as well as the Niryuktis, short commentaries on 10 of the 12 original sacred books. Some authorities say that, after the famine, Bhadrabahu retired in seclusion to Nepal; others say he remained in Mysore. He is reputed to have undergone the process of sallekhana, the Jain ritual of ultimate triumph over human passions in which the believer renounces the world completely and starves to death.
