This dhyana mantra is a contemplative tool for realizing the Mahavakya 'Prajnanam Brahma' (Consciousness is Brahman), which originates from the Aitareya Upanishad (3.3) of the Rigveda. The phrase is one of the four great sayings (mahavakyas) of Advaita Vedanta, declaring that pure consciousness (prajnanam) is identical with the ultimate reality (Brahman). The mantra is chanted to internalize this non-dual truth through meditative repetition. The term 'prajnanam' signifies supreme, self-luminous awareness that is the substratum of all experience.
According to the Aitareya Upanishad, 'Prajnanam Brahma' is the realization that the conscious self within is none other than Brahman, the universal consciousness. The mantra's beej-akshara is implicitly 'Om', which precedes the mahavakya in traditional chanting. Phonetically, the syllables 'pra-jñā-nam' emphasize the cognitive aspect of awareness, while 'brahma' resonates with the expansive nature of reality. The purpose of this dhyana mantra is to dissolve the duality between the individual self and Brahman, leading to liberation (moksha).
It is traditionally chanted during meditation (dhyana) in a quiet setting, preferably at dawn or dusk, with a japa mala of 108 repetitions. The recommended count is 108 times daily for 40 days to stabilize the realization. According to the Mantra-Yoga-Samhita, such mahavakya mantras purify the mind and awaken the intuitive knowledge of non-duality. No specific cautions are prescribed, but the practitioner should have a firm grounding in Vedantic study and be guided by a qualified guru, as the mantra's power can be destabilizing without proper understanding.
The Lalita Sahasranama also echoes this truth in the name 'Prajnanaghana' (mass of consciousness), affirming the identity of the Goddess with pure awareness. This dhyana mantra is not a ritualistic invocation but a meditative affirmation for those on the path of jnana yoga.
Consciousness is Brahman.
The mantra begins with the seed-syllable 'Oṁ', which is the primordial beej-akshara representing Brahman. The phrase itself is a mahavakya, not a beej-mantra.
