The Para Brahman Dhyana Mantra is a contemplative formula directed toward the Supreme Ultimate Reality, which is described in the Upanishads as nirguna (without attributes), nirakara (formless), and advaita (non-dual). The term 'Para Brahman' denotes the transcendent absolute beyond all names, forms, and conceptualizations. The mantra is not a specific string of syllables but rather a meditative focus on the nature of Brahman as expounded in scriptures such as the Bhagavad Gita (Chapter 8, verse 3: 'aksharam brahma paramam') and the Mandukya Upanishad, which identifies the fourth state (turiya) as the realization of the Self as Brahman.
The beej-akshara 'Om' is often included as the primal sound representing Brahman, as stated in the Mandukya Upanishad: 'Om ity etad aksharam idam sarvam.' The purpose of this dhyana mantra is to dissolve the meditator's identification with the body-mind complex and to abide in the non-dual consciousness of 'Aham Brahmasmi' (I am Brahman, from the Brihadaranyaka Upanishad 1.4.10) and 'Tat Tvam Asi' (That Thou Art, from the Chandogya Upanishad 6.8.7). Chanting is traditionally performed during the brahma muhurta (pre-dawn hours) in a seated posture with a calm mind, often after japa of Om or the Mahavakyas. The recommended count is not fixed; the emphasis is on quality of contemplation rather than quantity.
There are no specific ritual restrictions, but the practitioner should be established in ethical conduct (yama and niyama) as per the Yoga Sutras. Caution is advised: this mantra is not for those seeking worldly boons, as its sole aim is liberation (moksha). It is considered the highest form of meditation in the Advaita Vedanta tradition, as referenced in the Vivekachudamani of Shankaracharya.
The mantra transcends all deities and forms, leading directly to the realization of the Absolute.
Om, the Supreme Brahman.
The mantra contains the seed-syllable 'Om', which is the primary beej-akshara representing Brahman as per Mandukya Upanishad.
