Acharya Bhadrabahu
Acharya Bhadrabahu (c. 433–357 BCE) was the final Shruta Kevali—the last spiritual titan who possessed complete, flawless oral mastery over all 14 Purvas (the lost, original core scriptures of Jainism). Born in Pundravardhana (modern Bangladesh), his intellect and spiritual purity elevated him to become the sixth head of the entire Jain monastic congregation (Sangha). He is the author of foundational texts like the Bhadrabahu Samhita and the Kalpa Sutra.
When a devastating 12-year famine loomed over North India, threatening the physical survival of his monks and the preservation of scriptural knowledge, Bhadrabahu took the monumental decision to lead an exodus of 12,000 unclad ascetics to the safety of South India. He halted at the twin hills of Shravanabelagola due to failing health. As the supreme spiritual master, Acharya Bhadrabahu initiated the mighty Emperor Chandragupta Maurya into monkhood, leading him away from his vast imperial army to Shravanabelagola, where the emperor spent his final days serving his guru and meditating in the very same cave where Bhadrabahu attained liberation.
