Vitashoka

Vitashoka or Tissa (born 3rd-century BCE) was a prince of the Maurya Empire as the only uterine of Ashoka, and the only brother left alive by Ashoka. According to Divyavadana, he was a follower of the Tirthikas and used to criticize the Buddhist monks for living a comfortable life. He was made to sit on the throne by the courtiers. When Ashoka found out about that, he persuaded Vitashoka to become a Buddhist.

Vitashoka became a monk and practised austerities rigorously.
