1. Amba Jātaka (No. 124).-During a very severe drought a hermit, living in the Himālaya at the head of five hundred ascetics, provided water for the animals, using the hollowed trunk of a tree as trough. In gratitude the animals brought him various fruits, enough for himself and his five hundred companions. The story is related regarding a brother who was very zealous in his duties, doing everything well and wholeheartedly. Because of his great goodness the people fed regularly every day five hundred of the Brethren. J.i.449-51.
2. Amba Jātaka (No. 474).-The story of a brahmin youth who learnt a charm from a wise Candāla. The charm had the power of making lovely and fragrant mangoes grow out of season. The youth exhibited his skill before the king, but when asked the name of his teacher he lied and said he had been taught in Takkasilā. Immediately the charm escaped his memory and all his power deserted him. At the king's suggestion he went back to the teacher to ask his forgiveness and to learn the charm anew, but the teacher would have none of him and the youth wandered away into the forest and died there.
The story is told in reference to Devadatta who had repudiated the Buddha as his teacher and as a result was born in Avīci (J.iv.200-7).
The youth was a former birth of Devadatta.
