Temiyajātaka

Suttapiṭaka · Khuddakanikāya · Jātaka (2) · Vol. 28 · Section 437

[437] Let a youth live the holy life (brahmacariya); one who lives the holy life should be a youth; for the going forth (pabbajjā) of one who is young — this the seers have praised. Let a youth live the holy life; one who lives the holy life should be a youth; I shall live the holy life; I have no need of kingship. I see a young boy of yours, a child who calls "Mother! Father!" — a dear son, gained with hardship, dead without ever reaching old age. I see a young girl of yours, a maiden lovely to behold, come to the destruction of her life like a shoot of young bamboo torn off. For even the young die, both men and women; what man, then, could trust in life, thinking, "I am young"? He whose life grows ever less with the passing of each night, like that of fish in shallow water — what youthfulness is there in that? The world is constantly assailed, and constantly hemmed in; while [the nights] pass by, never in vain, why do you anoint me with kingship?
