From Jataka Tales
A very wealthy old man, imagining that he was on the point of death, sent for his sons and divided his property among them. However, he did not die for several years afterwards; and miserable years many of them were. Besides the weariness of old age, the old fellow had to bear with much abuse and cruelty from his sons. Wretched, selfish ingrates!
One day he met a friend and related to him all his troubles. The friend sympathized very much with him, and promised to think over the matter, and call in a little while and tell him what to do.
He did so; in a few days he visited the old man and put down four bags full of stones and gravel before him.
When the young men got to hear of this further increase of wealth they began to be more attentive and pleasing to their father than ever before. And thus they continued to the day of the old man’s demise, when the bags were greedily opened, and found to contain only stones and gravel!
