Angulimala the bandit saw the Buddha coming from afar and determined in his mind to pursue the contemplative and kill him.Then the Buddha willed a feat of psychic power such that Angulimala, though running with all his might, could not catch up with the Buddha walking at normal pace. So he stopped and called out to the Buddha, "Stop, contemplative! Stop!" the Buddha called back "I have stopped, Angulimala. You stop."
Bewildered by this, Angulimala decided to question the contemplative:
"While walking, contemplative, you say, 'I have stopped.' But when I have stopped you say I haven't. I ask you the meaning of this: How have you stopped? How haven't I?"
The Buddha: "I have stopped, Angulimala, once & for all, having cast off violence toward all living beings. You, though, are unrestrained toward beings. That's how I've stopped and you haven't." Angulimala: "At long last a greatly revered great seer for my sake has come to the great forest.
