Mundaka Upanishad

The Mundaka Upanishad belongs to the Atharva Veda and has three chapters, each of which has two sections. The name is derived from the root 'mund' (to shave) as he that comprehends the teaching of the Upanishad is shaved or liberated from error and ignorance. The Upanishad clearly states the distinction between the higher knowledge of the Supreme Brahman and the lower knowledge of the empirical world — the six 'Vedangas' of phonetics, ritual, grammar, definition, metrics, and astrology. It is by this higher wisdom and not by sacrifices or worship, which are here considered 'unsafe boats', that one can reach the Brahman. Like the Katha, the Mundaka Upanishad warns against "the ignorance of thinking oneself learned and going around deluded like the blind leading the blind". Only an ascetic ('sanyasi') who has given up everything can obtain the highest knowledge.
