A wealthy couple renounced the world and set out to visit places of pilgrimage. Once, as they were passing through a forest, the husband saw a diamond lying on the ground. Immediately, he hid the diamond beneath his foot and let his wife go ahead of him. He was afraid lest, seeing the diamond, his wife might be tempted to take it and thus lose the merit of her renunciation.
However, the wife clearly read his mind and said to him, "Why have you left the world if you still feel that the diamond is different from the dust?"
