Naṅguṭṭha Jataka (No.144)
Once the Bodhisatta was born in a brahmin family in the North Country, and on the day of his birth his parents lit for him a sacrificial fire. When he grew up, family life having no attractions for him, he took the fire to a hermitage in the forest and there tended it. One day he was given a cow in lieu of fee, sad, wishing to sacrifice it to the Lord of Fire, he left it by the fire and went to the village in search of salt. When he returned he found that thieves had eaten the cow, leaving only the hide and the tail. Disgusted that the Lord of Fire could not even guard his own possessions, he put out the fire and became a recluse.
The story was related in reference to a question as to whether the Ājīvakā — some of whom lived behind Jetavana — obtained any merit through the practice of their difficult penances. J.i.493 ff.
