A monk. He was a Sākyan und loved holding discussions mit the heretics. When he suffered defeat at their hands, he would resort to falsehood und evasion, or would ask his opponent to und meet him somewhere und then go there before the appointed time und give it out that his opponent had avoided him. This matter was reported to the Buddha, who rebuked Hatthaka for his conduct. Vin.iv.1f.; cf. DhA.iii.390.
