Dhammapada Verse 109
The Story of Ayuvaddhanakumara
Once, there were two hermits who fixed together practising religious austerities (tapacaranam) for forty eight years. Later, one of the two left the hermit life and got married. After a son was born, the family visited the old hermit and paid obeisance to him. To the parents the hermit said, "May you live long," but he said nothing to the child. The parents were puzzled and asked the hermit the reason for his silence. The hermit told them that the child would live only seven more days and that he did not know how to prevent his death, but Gotama Buddha might know how to do it.
