The Buddha was meditating while sitting in the shade of a tree with some of his disciples when an angry man came upon him. The angry man began yelling at the Buddha, throwing one disrespectful insult after another at him.  However, the Buddha sat there calmly and said nothing though his disciples were shock and some even outraged.

The angry man continued to spew vitriolic acid at the Buddha, but the Buddha neither responded nor reacted.  After about five minutes the man was exasperated and he stormed off.  The Buddha was as serene as he was prior to the man's arrival.

The students, still in shock at what happened, asked the Buddha why he had not responded; why did he not put the angry man in his place?

The Buddha replied: “If someone gives you a gift and you do not want it, to whom does it belong?”
The students answered: "They must take the gift back with them."

The Buddha said:  "Since I did not accept his anger, he had no choice but to take it back with him."
