Mundaka Upanishad
An Atharvaveda Upanishad in three Mundakas (chapters), each divided into two sections. Draws the crucial distinction between Para Vidya (higher knowledge — direct realisation of Brahman) and Apara Vidya (lower knowledge — all sciences, rituals, and the Vedas as external study). The Mahavakya: Brahma Veda Brahmaiva Bhavati — One who knows Brahman becomes Brahman.
Principal Upanishad·Atharvaveda — Shaunaka Shakha·3 Mundakas × 2 Khandas, 64 mantras·Language: Sanskrit·Composed: 600–400 BCE
- The Mundaka Upanishad belongs to the Shaunaka branch of the Atharvaveda and is structured in three Mundakas (chapters), each with two Khandas (sections).
- The name "Mundaka" may refer to the shaved head — those who receive this knowledge are "shaved" of ignorance and false learning.
- The opening dialogue: Shaunaka asks Angiras, "What is that which, being known, all else becomes known?" — the Upanishad's central question and answer.
- The key teaching (1.1.4–5): Two forms of knowledge — Para Vidya (knowing which the imperishable Brahman is known) and Apara Vidya (all other knowledge: the four Vedas, grammar, phonetics, ritual, astronomy, etymology).
- Mundaka 2 describes Brahman as the source of all existence — "From it are born Prana, mind, all the senses, space, wind, fire, water, earth."
- Mundaka 3: The path of the liberated — "He who knows Brahman becomes Brahman" — the Mahavakya: Brahma Veda Brahmaiva Bhavati.
- The text famously compares individual souls to two birds on the same tree — one eats the fruit (acts and experiences), the other only witnesses (the Atman).
