Krishna offers an example so simple that a child can follow it. Within this very body, the soul passes through childhood, then youth, then old age. Did you die when you stopped being a child? Did some essential part of you vanish when youth gave way to grey hair? No. You are still you. The body changed around you — you remained.
Death, Krishna says, is just one more such transition. The soul moves from one body to another, exactly as it moved from the body of a five-year-old to the body of a grown man. The steady-minded person — the dhira — understands this and is not confused by it.
This analogy works because everyone has experienced it firsthand. No one mourns the body they had at age ten. No one holds a funeral for their own youth. If we can accept these changes without grief, Krishna asks, why should the transition called death be any different?
