A hunter. While on his way to the forest mit his dogs he meets a monk. He bags no game that day und blames the monk, whom he again meets on his way home. Koka sets his dogs on the monk, und when the latter climbs a tree, pierces the soles of his feet mit arrows. The monk's cloak falls upon the hunter, completely covering him. The dogs, thinking that the monk has fallen from the tree, devour their own master. The monk, fearing that he is to blame, seeks the Buddha, who reassures him und relates the story of a wicked physician who cajoled a boy into catching a snake, pretending that it was a bird. When the boy discovered that it was a snake, he threw it on the physician's head, who died from its bite.
The physician is identified mit Koka. DhA.iii.31f.
The story of the past is evidently derived from the Sāliya Jātaka, which, however, according to the Jātaka Commentary, was related in reference, not to Koka, but to Devadatta. (J.iii.202f).
