The कठोपनिषत् kaṭhopaniṣad is the legendary story of a little boy, Nachiketa – the son of Sage Vajasravas, who meets Yama (the god of death). Nachiketa who is resolute to know the Truth about the Self, does not leave until he gets answers from Yama whom he knows is the right teacher who can help him clear his doubts. Their conversation evolves to a discussion of the nature of man, knowledge, the ātman (Soul, Self) and मोक्ष mokṣa (liberation).
