A monk in his travels once found a precious stone and kept it.
One day he met a traveler, and when the monk opened his bag to share
his provisions with him, the traveler saw the jewel
and asked the monk to give it to him.
The monk did so readily.

The traveler departed, overjoyed with the unexpected gift of the precious stone
that was enough to give him wealth and security for the rest of his life.
However, a few days later he came back in search of the monk,
found him, gave him back the stone, and entreated him,

“Now give me something much more precious than this stone,
valuable as it is. Give me that which enabled you to give it to me.”
