Owing to his great saintliness, even the gods vied with each other to give alms to Kassapa. Once when he had risen from a trance lasting seven days, five hundred nymphs, wives of Sakka, appeared before him; but, snapping his fingers, he asked them to depart, saying that he bestowed his favours only on the poor.
The story of KÄlavilangika is an example of Kassapaâs compassion for the poor. Once, after a seven daysâ trance, he went to the house of KÄlavilanga and received alms from his wife, which he gave to the Buddha for their greater benefit. The Buddha took a portion of this and gave the rest to five hundred monks. KÄlavilangika, received only a mouthful of the food left. The Buddha said that as a result he would be a setthi within seven days. KÄlavilangika told this to his wife. It happened that a few days later the king saw a man impaled alive in the place of execution; the man begged him for some food, which he agreed to send. At night, when eating, the king remembered his promise, but could find no one bold enough to go to the cemetery. On the offer of one thousand pieces, KÄlavilangikaâs wife agreed to go in the guise of a man. On the way she was stopped by the yakkha DÄ«ghataphala, who, however, later released her and gave her treasure, as did also the yakkhaâs father in law, the deva Sumana. The man ate the food and, when wiping his mouth, recognised her as a woman and caught hold of her hair. But she cut off her hair, and proved to the satisfaction of the king that her mission had been accomplished. She then recovered the treasure given her by the yakkha and Sumana; when the king discovered her wealth, she and her husband were raised to the rank of setthi (MA.ii.812ff.).
When Sakka heard of this, he disguised himself as a weaver worn with age, and accompanied by SujÄtÄ, transformed into an old woman, appeared in a weaverâs hut along the lane where Kassapa was begging. The ruse succeeded and Kassapa accepted their alms; but, later, be discovered the truth and chided Sakka. Sakka begged forgiveness, and, on being assured that in spite of his deception the almsgiving would bring him merit, he flew into the air shouting, âAho dÄnam, mahÄ danam, Kassapassa patitthitam.â The Buddha heard this and sympathised with Sakka in his great joy (DhA.i.423ff.; cp. Ud.iii.7).
But on one occasion so great was the importunity with which the monks of Alavi had wearied the people, that even MahÄ Kassapa failed to get alms from them (J.ii.282). The Visuddhi Magga (403) relates a story of how once, when Kassapa was begging for alms in RÄjagaha, in the company of the Buddha, on a festival day, five hundred maidens were going to the festival carrying cakes, âround like the moon.â They saw the Buddha but passed him by, and gave their cakes to Kassapa. The Elder made all the cakes fill just his single bowl and offered it to the Buddha (This is probably the incident referred to at Vsm.68).
