Kosiya; 1. Kosiya Jataka (No.130) - A brahmin of Benares had a bad wife who lay in bed by day feigning sickness and spent her nights in enjoyment. The husband worked hard to supply her with dainties, and, in consequence, could not visit his teacher who was the Bodhisatta. When the latter discovered the truth, he advised the brahmin to prepare a mess of cow dung and other things and to insist that his wife should either swallow this medicine or get up and work. She then knew that her shamming was discovered and abandoned her evil ways.
The story was told to a brahmin of Savatthi, a pious follower of the Buddha, whose wife behaved in a similar way. The Buddha told him this story of the past and asked him to try the same remedy, for, he said, the brahmin and his wife were identical with the couple of the story (J.i.463f).
2.Kosiya Jataka (No.226) - The king of Benares, making war at an unseasonable time while camping in the park, saw an owl (kosiya) being attacked by crows. The king asked his minister the reason for this; the minister, being the Bodhisatta, said the owl had left his hiding place too early that is, before sunset.
