The Niralamba Upanishad Dhyana Mantra is a meditative verse from the Niralamba Upanishad, a minor Upanishad of the Shukla Yajurveda tradition. The term 'Niralamba' means 'without support' or 'supportless,' and the Upanishad expounds the non-dual (Advaita) nature of the Self (Atman) as identical with Brahman, the ultimate reality that requires no external support. The dhyana mantra is used for contemplation on this supportless, self-luminous consciousness. According to the Niralamba Upanishad itself (verses 1-2), the mantra guides the aspirant to realize the Self as devoid of all attributes, free from the three states of waking, dream, and deep sleep, and as the witness (sakshi) of all.
The mantra typically begins with 'Om' and invokes the formless Brahman. The beej-akshara 'Om' represents the primordial sound and the entirety of existence, while the subsequent phrases negate all supports (niralamba) and affirm the sole reality of the Self. The traditional purpose of chanting this mantra is to attain liberation (moksha) through direct realization of one's own nature as the supportless, non-dual consciousness. It is recommended to be chanted during the Brahma Muhurta (pre-dawn hours) in a quiet, solitary setting, with a count of 108 repetitions using a rudraksha mala.
The practitioner should sit in a comfortable meditative posture, focus on the space between the eyebrows, and contemplate the meaning of the mantra. Cautions include that this mantra is intended for those with a strong foundation in Vedantic study and dispassion (vairagya); it may be destabilizing for unprepared minds. The mantra is also referenced in the commentary by Shankaracharya on the Upanishads, where he emphasizes the need for a qualified teacher. The Niralamba Upanishad states that one who knows this supportless reality becomes free from all bonds (verse 10).
Thus, the dhyana mantra serves as a direct means to realize the Advaitic truth.
Om. Let us meditate on the Supportless One. Let us contemplate the Void-formed. May that Brahman impel us.
The mantra contains no explicit seed-syllables beyond Oṁ, which is the primordial beej. The structure is a modified Gayatri meter, but the core is the negation of attributes (nirālamba, śūnyākāra).
