According to the "Ashokavadana", a non-Buddhist in Pundravardhana drew a picture showing the Buddha bowing at the feet of the Nirgrantha leader Jnatiputra. The term nirgrantha ("free from bonds") was originally used for a pre-Jaina ascetic order, but later came to be used for Jaina monks. "Jnatiputra" is identified with Mahavira, 24th Tirthankara of Jainism. The legend states that on complaint from a Buddhist devotee, Ashoka issued an order to arrest the non-Buddhist artist, and subsequently, another order to kill all the Ajivikas in Pundravardhana. Around 18,000 followers of the Ajivika sect were executed as a result of this order. Sometime later, another Nirgrantha follower in Pataliputra drew a similar picture. Ashoka burnt him and his entire family alive in their house. He also announced an award of one dinara (silver coin) to anyone who brought him the head of a Nirgrantha heretic. According to "Ashokavadana", as a result of this order, his own brother was mistaken for a heretic and killed by a cowherd. Ashoka realised his mistake, and withdrew the order.
