DESCRIPTION:
Tisziji on all tracks, all instruments. "HU" Meditation Chant from home recordings made by Tisziji Munoz in the 1980s for meditation and healing use. These were never intended for public release but were recorded for his son, and are therefore a very pure document of Tisziji's musical yoga, Ati Agni Surat Shabd Yoda, or Ultimate Fire-Sound Realization.

from Wiki: Surat Shabd Yoga or Surat Shabda Yoga is a form of spiritual practice that is followed in the Sant Mat and many other related spiritual traditions. Surat means "attention," or "face," which is the outward expression of the soul, shabd means "word" and yoga means "union." The term "word" means the "Sound Current," the "Audible Life Stream" or the "Essence of the Absolute Supreme Being," that is, the dynamic force of creative energy that was sent out, as sound vibration, from the Supreme Being into the abyss of space at the dawn of the universe's manifestation, and that is being sent forth, through the ages, framing all things that constitute and inhabit the universe.

The etymology of "Surat Shabda Yoga" presents its purpose: the "Union of the Soul with the Essence of the Absolute Supreme Being." Other expressions for Surat Shabda Yoga include Sehaj Yoga (an easy path leading to Sehaj or equipoise) The Path of Light and Sound, The Path of the Sants, The Journey of Soul, and The Yoga of the Sound Current.
The stated purpose of Surat Shabda Yoga is to realize the individual's True Self (Self-Realization), True Essence (Spirit-Realization) and True Divinity (God-Realization) while living in the human physical body. This Journey of Soul involves reuniting in stages with what is called the Essence of the Absolute Supreme Being, the Shabd. Attaining self-realization and above also results in jivan moksha/mukti, liberation/release from samsara, the cycle of karma and reincarnation while in the physical body. "
