Nachiketa said: Look back and see how it was with those who came before us and observe how it is with those who are now with us. A mortal ripens like corn and like corn he springs up again.
Swami Vivekananda Says —
Birth, growth, development, decay, death — this is the sequence in all nature and is the same in the plant and the man.[Source]
And the story goes on to say that the boy went to Yama, the god of death. Yama was the first man who died. He went to heaven and became the governor of all the Pitris; all the good people who die, go, and live with him for a long time. He is a very pure and holy person, chaste and good, as his name (Yama) implies.[Source]
