`Look back how it was with those who came before, look forward how it will be with those who come hereafter. A mortal ripens like corn, like corn he springs up again.' (Nakiketas enters into the abode of Yama Vaivasvata, and there is no one to receive him. Thereupon one of the attendants of Yama is supposed to say:) enters as a guest. That fire is quenched by this peace-offering; bring water, O Vaivasvata! man without receiving food to eat, destroys his hopes and expectations, his possessions, his righteousness, his sacred and his good deeds, and all his sons and cattle.' (Yama, returning to his house after an absence of three nights, during which time Nakiketas had received no hospitality from him, says:) dwelt in my house three nights without eating, therefore choose now three boons. Hail to thee! and welfare to me!'
