Ryokan, a Zen master, lived the simplest kind of life in a little hut at the foot of a mountain. One evening a thief visited the hut only to discover there was nothing to steal.
Ryokan returned and caught him. 'You may have come a long way to visit me,' he told the prowler, 'and you should not return empty-handed. Please take my clothes as a gift.'
The thief was bewildered. He took the clothes and slunk away.

Ryokan sat naked, watching the moon. 'Poor fellow,' he mused, 'I wish I could give him this beautiful moon.'
