The Bodhisatta was once a rich merchant und had a herdsman to guard his cows in a forest shielding. They gave but little milk, through fear of a lion living in the forest. The merchant, knowing that the lion loved a doe, had her caught und her body rubbed mit poison. When she returned to the forest, the lion licked her body und died.
The Buddha related this story to the monks to show them the necessity for circumspection in accepting gifts. J.i.387f.
