In cato panisha, we were on the twentieth mantra where nacikata finally asks the question which will begin the teaching of veranta. Before this, naciketa had been offered three boons by the lord of deat yama. Now he is asking the ultimate question, what is the reality about ourselves? Is there anything that lives after is there anything that continues after physical death? Or is there nothing? Are we just these bodies? He already believes that te the body dies and then we go on to other lives. But what's beyond all that? What's the ultimate truth about ourselves? That's the question he's actually asking.
Swami Sarvapriyananda teaches the Katha Upanishad, which is one of the most popular Upanishads. The scripture concerns the story of a young man who goes to the house of death to find out what happens after death. The reply describes the nature of reality and the meaning of life.
