The Anahata Nada Dhyana Mantra is a meditation on the unstruck sound (anahata nada) that arises spontaneously in the heart center during deep meditative states. The term 'anahata' means 'unbeaten' or 'unstruck,' referring to a sound that is not produced by any physical collision, as described in the Nada Bindu Upanishad (verses 32-41). This Upanishad explains that by focusing on the subtle inner sound, the yogi transcends the mind and attains the supreme state.
The mantra is associated with Nada Brahman, the absolute as sound, and is central to the practice of nada yoga, which aims to merge individual consciousness with the cosmic vibration. According to the Hatha Yoga Pradipika (Chapter 4, verses 64-102), the anahata nada is heard in the right ear during advanced pranayama and meditation, leading to the dissolution of the mind. The practice involves sitting in a comfortable posture, closing the ears with the thumbs, and listening intently to the subtle sounds within, progressing from gross to subtle until only the unstruck sound remains.
The recommended chanting context is during early morning or late evening, in a quiet space, with a count of 108 repetitions or for extended periods of listening. The purpose is to open the heart chakra (anahata), purify the nadis, and realize the unity of the individual self with the cosmic sound. Cautions include the need for a steady mind and gradual practice, as forcing the experience can lead to mental agitation.
The mantra is not typically chanted aloud but rather used as a focus for inner listening, aligning with the yogic tradition of shravana (hearing) as a means of meditation.
