Dharma Talk: No Loving-Kindness

There was an old woman in China who supported a monk for over twenty years. She built a little hut for him and fed him while he was meditating. Finally, she wondered just what progress he had made in all this time. To find out, she obtained the help of a young woman rich in desire. "Go and embrace him," she told her, "and then ask him suddenly: 'What now?'"

The young woman called upon the monk and without much ado caressed him, asking him what he was going to do about it.
"An old tree grows on a cold rock in winter," replied the monk somewhat poetically. "Nowhere is there any warmth."
The young woman returned and related what he had said.
"To think I fed that fellow for twenty years!" exclaimed the old woman in anger. "He showed no consideration for your need, no disposition to explain your condition. He need not have responded to passion, but at least he could have evidenced some compassion."

She at once went to the hut of the monk and burned it down.
