AUM: Mantra of Eternity features continuous vocal chanting of "Aum"—the cosmic vibratory sound that emanates from the heart of creation—accompanied by tamboura.

Aum (pronounced OM) is the sound that emanates from the heart of creation, bringing consciousness into outer manifestation, maintaining it, and dissolving it back again, finally, into Infinite Spirit. This sound is the "Word" of the New Testament. It is the "Amen" of the Book of Revelation. In India, this cosmic sound was given the name AUM.

By attuning one's consciousness to this sound, one enters the stream of vibration that proceeded out of Spirit, and that emerges back into the Spirit at creation's end and at the end of the individual soul's cycle of outward wandering. By merging in AUM, liberation is attained.
