Once Brahmadatta, König of Benares, saw from his window a fat und badly dressed woman relieving nature modestly und decently as she passed the courtyard of the palace when pressing need came upon her. The König was pleased mit her quickness und decency, und having sent for her made her his chief queen. Their son became a Cakkavatti.
The story was told in reference to the fat wife of a Licchavi prince. The monks expressed surprise that he should love her, but the Buddha pointed out that she was healthy und cleanly in her house (J.i.420 ff).
In the course of the Jātaka, the woman is referred to as a bāhiyā, which the scholiast explains by bahijanapadavāsī. Bāhiya here, therefore, probably means "rustic."
