Mbh 13.93.8

"'Bhishma said, "The Brahmana accepts gifts from him that is righteous, and from him that is unrighteous. If the giver happens to be righteous, the receiver incurs little fault. If on the other hand, the giver happens to be unrighteous the receiver sinks in hell. In this connection is cited an old history of the conversation between Vrishadarbhi and the seven Rishis, O Bharata. Kasyapa and Atri and Vasishtha and Bharadwaja and Gautama and Viswamitra and Jamadagni, and the chaste Arundhati (the wife of Vasishtha), all had a common maidservant whose name was Ganda. A Sudra of the name of Pasusakha married Ganda and became her husband. Kasyapa and others, in days of old, observed the austerest penances and roved over the world, desirous of attaining to the eternal region of Brahman by the aid of Yoga-meditation. About that time, O delighter of the Kurus, there occurred a severe drought. Afflicted by hunger, the whole world of living creatures became exceedingly weak. At a sacrifice which had been performed in former times by Sivi's son he had given away unto the Ritwiks a son of his as the sacrificial present. About this time, unendued with longevity as the prince was, he died of starvation. The Rishis named, afflicted with hunger, approached the dead prince and sat surrounding him. Indeed, those foremost of Rishis, beholding the son of him at whose sacrifice they had officiated, O Bharata, thus dead of starvation, began to cook the body in a vessel, impelled by the pangs of hunger. All food having disappeared from the world of men, those ascetics, desirous of saving their lives, had recourse, for purposes of sustenance, to such a miserable shift. While they were thus employed. Vrishadarbha's son, viz., king Saivya, in course of his roving, came upon those Rishis. Indeed, he met them on his way, engaged in cooking the dead body, impelled by the pangs of hunger.
