Nadabindu and Dhyanabindu Upanishads: Meditations on the Inner Sound

Included is a foreword on the life and teachings of Swami Satyadharma, who passed away while writing the commentary on Dhyanabindu. Her commentary on Nadabindu is complete. The Dhyana and Nadabindu Upani¿ads were probably composed between the ninth and fourteenth centuries CE. The bindu is a psychic centre located in the brain at the top back of the head. These upani¿ads focus on meditation on the bindu, the source point or origin of individual creation, where begins the primal sound or first vibration, the mantra Om. They define and describe in detail the mantra Om, the effects of meditating on it until one attains perfect liberation, merging with the Divine.Nadabindu describes the components of Om, that is, its three and a half measures (matra) which are the sounds a u m, and the half measure, the echo of m. Always meditating on Om, the yogin is liberated from worldly life, unaffected by his/her karmas. The nada is first heard through the right ear, and many other inner sounds are heard. Eventually the yogin hears no other sounds and transcends duality.Dhyanabindu, an expansion of Nadabindu, confirms that meditation on Om can destroy all karmas. The yogin should meditate on the lotus of the heart, then at the eyebrow centre, then on the Sun, Moon and Agni, leading to the atman. The six parts of yoga, the cakras, na¿is and pra¿as are described. Ku¿¿alini Sakti can be awakened by the repetition of the mantra ha¿sa, ham spontaneously accompanying the inhalation, and sa the exhalation, as well as u¿¿iyana and jalandhara bandhas, khecari mudra and mahamudra. The atman is described in detail. Finally, the teacher recommends meditating on the bija mantras of the five elements, the five pra¿as and the nada.
