Devadatta felt very powerful, because the new king was his
friend and supporter. So he decided to kill the Buddha. One
evening, while the Buddha was walking past a rocky hill, Devadatta
pushed a huge stone down the hillside, intending to kill the
Buddha. But the rock suddenly broke into many pieces and only
one sharp piece hit the Buddha, on his foot. The Buddha returned
to the monastery and was treated by the famous physician Jivaka.
