According to Jain tradition, which religion did Chandragupta Maurya adopt and who guided him?

Later Jain tradition associates Chandragupta Maurya’s final years with acceptance of Jain discipline under the teacher Bhadrabahu and migration to Shravanabelagola. This question belongs to the political, religious and diplomatic history of the Mauryan age. A sound answer requires matching the ruler, person, place, title or event with its correct chronological and documentary setting. Mauryan history is reconstructed from several different bodies of evidence: Ashokan inscriptions, archaeological remains, the Arthashastra tradition, Buddhist and Jain narratives, Puranic genealogies, and Greek or Roman accounts. These sources were produced at different times and for different purposes, so their claims should not automatically be treated as identical in reliability.
