Katha Upanishad
A poetic Upanishad of the Krishna Yajurveda in two parts and six chapters. The dialogue between young Nachiketa and Yama (god of death) reveals the secret of immortality, the indescribable Atman, and the two paths — Shreyas (the good) and Preyas (the pleasant). Source of the celebrated verse: Uttishtata Jagrata — Arise! Awake! (used by Swami Vivekananda).
Principal Upanishad·Krishna Yajurveda — Katha Shakha·6 chapters (Vallis) in 2 Adhyayas, ~120 verses·Language: Sanskrit·Composed: 500–300 BCE
- The Katha Upanishad is the most celebrated poetic text in the Upanishadic canon — the dialogue between the young boy Nachiketa and Yama, the god of death.
- Nachiketa is sent by his father Vajashrava to Yama's realm; Yama is absent for three nights and must grant Nachiketa three boons as compensation.
- The first boon: peace with his father. The second: the fire sacrifice for heaven. The third — and the heart of the text — is the secret of what happens after death.
- Yama tries to dissuade Nachiketa with offers of wealth, pleasure, and power; Nachiketa refuses all, asking only: "What lies beyond death?"
- Yama then reveals the indestructible Atman — "It is not born, it does not die; it was not produced by anything and nothing was produced from it; ancient, unborn, eternal, this primeval one is not slain when the body is slain."
- The text also introduces the doctrine of Shreyas (the good) vs Preyas (the pleasant) — most people follow Preyas; only the wise choose Shreyas.
- The famous verse: "Arise! Awake! Having reached the great teachers, know this — sharp as a razor's edge, hard to cross, the path is difficult; that is what the wise say" — adopted by Swami Vivekananda as his motto.

Key Topics
Atman is Unborn & Eternal
"Na jayate mriyate va — It is not born, nor does it die" (1.2.18–19) — the Atman is beyond death; Nachiketa's question is answered
Shreyas vs Preyas
The good (Shreyas) vs the pleasant (Preyas) — "The wise one who knows the difference between the two chooses the good over the pleasant; the fool chooses pleasure and misses the goal" (1.2.2)
Uttishtata Jagrata
"Arise! Awake! Attain the knowledge from the great teachers" (1.3.14) — Vivekananda's motto; the call to wake from the sleep of ignorance
Purusha in the Heart
"The Purusha (self) is the size of a thumb, dwelling in the cave of the heart — knowing him as the Lord, one is freed from all bonds" (2.1.12)
The Chariot Metaphor
Body = chariot; Atman = passenger; intellect = charioteer; mind = reins; senses = horses — the famous analogy for the spiritual path (1.3.3–9)
Key Figures
Nachiketa
The exemplary student — refuses all worldly temptations from Yama to ask about the supreme Atman; symbol of pure spiritual aspiration
Yama
God of death — the unexpected teacher; his reluctance to reveal the secret only deepens its significance when he does reveal it
Vajashrava (Aruni)
Father of Nachiketa — his ritual giving of old cows prompts Nachiketa to challenge him, setting the story in motion
Swami Vivekananda
Used Uttishtata Jagrata as his keynote; said the Katha Upanishad contains "the greatest thing ever uttered" in religious literature
