The most poetic and dramatically compelling of all the principal Upanishads. A boy named Nachiketa goes to the house of Death and refuses to leave until he is taught the secret of the self. Death itself becomes the teacher.
A man named Vājaśravasa performs a great sacrifice and gives away all his possessions as gifts — but gives away only old and barren cattle, the ones no longer of use. His young son Nachiketa watches and is troubled: gifts given without faith, without sincerity, lead nowhere. He asks his father: to whom will you give me?
His father, annoyed, finally snaps: I give you to Death. Nachiketa takes this literally. He goes to the house of Yama — Death — and waits. Death is away for three days. When Yama returns and finds the boy, he is embarrassed to have left a guest unfed for three nights. He offers Nachiketa three boons — one for each night.
Nachiketa's first boon: peace for his father. Granted. Second boon: teach me the Nachiketa fire — the fire ritual that leads to heaven. Granted. Third boon: this is the one. When a person dies, some say he continues; others say he does not. Teach me the truth of this.
Death tries to dissuade him. He offers wealth, kingdoms, beautiful women, anything at all in the world of the living. Take anything else as your third boon. Nachiketa refuses each offer in turn. None of those gifts can outlast death. I am at the house of Death and I am asking about what death cannot touch. Teach me.
Death, recognising in Nachiketa the rarest quality — a student who genuinely does not want what the world offers — gives the teaching. What follows is the Kaṭha Upaniṣad's philosophical content: the self that is not born and does not die, subtler than the subtle, greater than the great.
