This beautiful chant is by the vocal group On Wings of Song directed by Robert Gass. "Heart of Perfect Wisdom" features chanting by the men's choir; it's deep and full of Zen overtones, Tibetan bells, and singing bowls which produce extremely low frequencies. The sounds are so massive, the piece will almost massage your body.
The is piece is based on a Sanskrit chant which translates: "Gone, gone. Gone beyond. Gone beyond the beyond. Hail to the awakened one!"
