Once, Brahmadatta, king of Benares, discovered one of his courtiers intriguing in his harem. But being fond both of the man and the woman concerned, he asked advice of his counselor, the Bodhisatta, in a riddle that a pretty lake at the foot of a hill was being used by a jackal, while the lion lay quiet through it all. The counsellor's answer was that all creatures drink at will of a mighty river, yet the river is a river for all that. The king understood the answer and advised both those concerned.
The story was related to the king of Koala who had detected a similar happening in his court. J.ii.125ff.
