The Mundaka Upanishad, part of the Atharvaveda, presents the profound teaching of Brahmavidya (knowledge of Brahman) through a series of dhyana mantras. The text opens with the distinction between two kinds of knowledge: the higher (para) and the lower (apara). According to Mundaka Upanishad 1.1.4-5, the lower knowledge comprises the Vedas and their auxiliaries, while the higher knowledge is that by which the imperishable Brahman is known. The dhyana mantras focus on the contemplation of Brahman as the ultimate target, using the metaphor of the bow and arrow.
Mundaka Upanishad 2.2.3-4 instructs: 'Taking the bow of Om (the great weapon), place the arrow of the self (atman) upon it; then, drawing the bow with a mind fixed on Brahman, hit the mark, O dear one. Om is the bow, the self is the arrow, Brahman is the target; it is to be struck by an undistracted mind; one should become one with Brahman, like the arrow with the target.' This imagery underscores the meditative process where Om (pranava) serves as the bow, the individual self (jivatman) as the arrow, and Brahman as the target. The beej-akshara 'Om' is central, representing the primordial sound and the essence of the Vedas. The mantra is traditionally chanted for the attainment of liberation (moksha) and for deepening one's understanding of the non-dual nature of reality.
The recommended chanting context includes daily practice during brahma muhurta (pre-dawn hours), with a count of 108 repetitions using a rudraksha mala. It is also chanted during Vedantic study sessions and meditation retreats. Cautions: This mantra is considered highly potent and should be approached with reverence and proper guidance from a qualified guru. It is not recommended for those without a foundation in Vedantic philosophy, as the concepts require careful contemplation.
The Mundaka Upanishad itself (1.2.12-13) warns that the knowledge of Brahman is not attained by mere study but through sincere devotion and the grace of a teacher. Thus, the mantra is best practiced under the supervision of a competent preceptor.
I meditate on the knowledge of Brahman.
The mantra contains the seed-syllable 'Oṁ' (प्रणव), which is the primary beej-akshara representing Brahman and the essence of the Vedas.
