A non-Buddhist asked the Buddha, 'I do not ask for words, I do not ask for non-words.' The Buddha remained silent. The non-Buddhist said, 'The World-Honored One's great mercy has cleared away my delusions and enabled me to enter the path,' and he left. Ananda asked the Buddha, 'What did he realize?' The Buddha said, 'A good horse runs even at the shadow of the whip.'
