Upāhana Jātaka

Jataka No. 231 of the Pali Canon was told by the Buddha concerning the base ingratitude of Devadatta, a rival disciple who repeatedly sought to harm him. To show how old a pattern such ingratitude truly was, the Buddha recalled a story of an elephant trainer and the pupil he had once welcomed as his own son.

In Benares, the Bodhisatta was born the son of an elephant trainer and grew up skilled in managing elephants. When a young villager from Kāsi came to learn the craft, the Bodhisatta took him in. He taught him every chant, maneuver, and command without holding back any secret of the art, and when the pupil wished to serve the king, he presented him at court.

Once trained, the pupil let vanity take hold of him. The king would pay him only half of what his master received, but the pupil insisted that he knew all his teacher's skills piece for piece and would serve only for equal pay. The king agreed, on condition that the pupil show skill for skill with his master in a public exhibition the next day, and the pupil confidently accepted.

Knowing exactly what kind of character he was dealing with, the Bodhisatta, thinking that his pupil did not know all his resources, spent the night teaching one elephant to do everything awry. It would back up when told to go forward, go forward when told to back up, lie down when told to rise, and drop what it was told to pick up.

On the appointed day, with a great crowd gathered in the palace courtyard, both men displayed their skill, the pupil on a fine elephant of his own. Then the Bodhisatta gave his elephant reversed orders, and it did exactly the opposite of each command, to the astonishment of the onlookers. The pupil had no answer to a trick he had never been taught.

The onlookers had gathered expecting to see a genuine contest of skill, and instead saw the pupil's presumption exposed. They cried out at him for raising himself against his own master, not knowing his own measure, and pelted him with clods and staves, so that he died on the spot.

Coming down from his elephant and approaching the king, the Bodhisatta spoke two verses that gave the story its name. A pair of slippers bought at real cost to comfort the feet can still turn, if poorly made, to pinch and tear at the very skin they were meant to protect. An ungrateful pupil, raised and trained with real care, can turn in the end to torment the master who gave him everything he knew.

At the story's end, the Buddha identified the treacherous pupil with Devadatta. The very presumption which had once turned a trained elephant-man against the teacher who taught him everything was the same ingratitude Devadatta still carried toward the one who had shown him just as much patient instruction in this life.

What the trainer's verse captured was never really about shoes or elephants at all. It was about the particular danger of raising someone's skill without also shaping their character. A craft taught in full to an ungrateful heart becomes, soon enough, nothing more than a sharper tool for that same heart to use against the very hand that sharpened it. The Bodhisatta had asked for nothing from his pupil but honesty about what he had actually learned. It was the pupil's own refusal to offer even that much that turned a generous teacher's kindness into the very trap that finally caught him. A master who gives everything he knows still cannot give the one thing that keeps a skill from turning against him: a student's own willingness to remain, in his heart, still a student.
