The Yakkha and the Bodhisatta : หน้า 16/131

And thenceforth the Yakkha whenever she captured men, also took their clothes and rice and oil and the like, and serving him with various dainty food she herself would eat man’s flesh. And whenever she went away, for fear of his escaping, she closed the mouth of the cave with a huge stone before leaving. And while they were thus living amicably together, the Bodhisatta passing from his former existence was conceived in the womb of the Yakkha by the brahmin. After ten months she gave birth to a son, and filled with love for the brahmin and her child, she fed them both. By and bye when the boy was grown up, she put him also inside the cave with his father, and closed the door. Now one day the Bodhisatta knowing she had gone away removed the stone and let his father out. And when she asked on her return who had removed the stone, he said, “I did, mother: we cannot sit in darkness.” And through love for her child she did not say another word. Now one day the Bodhisatta asked his father, saying, “Dear father, your mouth is different from my mother’s; what is the reason?” “My son, your mother is a Yakkha and lives on man’s flesh, but you and I are men.” “If so, why do we live here? Come, we will go to the haunts of men.” “My dear boy, if we shall try to escape, your mother will kill us both.” The Favorite Jatakas
