The Nada Bindu Dhyana Mantra is a meditative formula centered on the inner sound (nada) and the point or drop (bindu). Its textual origin is primarily the Nada Bindu Upanishad, a minor Upanishad associated with the Rigveda, which expounds the yoga of sound and the dissolution of the mind into the supreme consciousness. The mantra is also referenced in later yoga texts such as the Yoga-Shikha Upanishad and the Hatha Yoga Pradipika, which describe the practice of listening to the inner sound to achieve samadhi. The deity associated with this mantra is Nada Brahman, the absolute reality conceived as sound. The beej-akshara (seed syllable) is 'Om', which represents the primordial vibration from which all creation emanates.
The bindu, often visualized as a dot or point, symbolizes the unmanifest source of sound. Phonetically, the mantra utilizes the resonance of 'Om' to guide the practitioner's awareness inward. The traditional purpose of this mantra is to facilitate concentration (dharana) and absorption (samadhi) by focusing on the subtle inner sounds that arise during deep meditation. According to the Nada Bindu Upanishad, by meditating on the nada, the mind becomes steady and merges into the supreme self. The recommended chanting context includes a quiet, undisturbed setting, preferably during brahma muhurta (pre-dawn hours).
The practitioner should sit in a comfortable asana, close the eyes, and mentally repeat the mantra while listening to the internal sound. The count is not fixed, but the practice is sustained until the mind dissolves into the sound. Traditionally, the mantra is chanted mentally (manasika japa) rather than aloud, as the goal is to perceive the subtle nada. Cautions include the need for a qualified guru, as the practice can lead to altered states of consciousness. Those with mental instability should approach with care.
The mantra is considered a direct means to realize the unity of sound and silence, leading to liberation.
