The Bodhisatta was once a landowner. His friend was an old man with a young wife. The old man felt certain that after his death his wife would remarry and spend all his money rather than giving it to his son. To thwart her, he buried his fortune in the forest, telling only his slave where the money lie. The old man instructed his slave to not let anyone sell the land and to take his son there when he became an adult.
When the son grew up, his mother told him of his father’s plan and said it was time that he go get his fortune. The slave took the son to the forest, but when they got there he grew pompous and insulted his master with “You servant of a slave-wench’s son! You don’t deserve to have this money?” The son, a gentleman, pretended he did not hear these words and decided to return home. A few days later they returned to the forest and again came back with nothing after the slave hurled more abuse.
The son decided to seek advice from his father’s friend, the Bodhisatta, who explained that since the thought of keeping the money himself was what caused the slave’s change in attitude, it must be buried right at the place where he speaks ill. So he advised that when the slave begins to talk, the son should take the spade and dig for the gold and jewels himself, then make the slave carry the treasure back. The son did as suggested and found that the Bodhisatta was right. With his father’s wealth and the Bodhisatta’s wisdom, he lived a happy life, giving charity and doing good deeds.
In the Lifetime of the Buddha
One time when Sariputta, one of the Buddha’s chief disciples, went on an alms pilgrimage, one of his co-resident pupils who came along had a drastic change in behavior. Normally meek and obedient, he turned haughty and insubordinate because of the attention he received during the trip. But, upon returning to the monastery, he reverted back to his natural docile self.
The slave was an earlier birth of this pupil and the Buddha told Sariputta this story so he knew he had shown the same odd, inappropriate behavior in the past.
