A short, simple melody, especially one characterized by single notes to which an indefinite number of syllables are intoned, used in singing the psalms, canticles, etc., in the church service. In both East and West, the name of God is chanted over and over again in the ritual of atonement whereby the soul of man becomes one with the Spirit of God by intonation of the sound of His name. This is given in Sanskrit as AUM or AUM TAT SAT AUM and in English as I AM THAT I AM.
By sounding the name of God or that of a member of the heavenly hosts, the vibration of the being is simulated and thereby Being itself is drawn to the one chanting. Therefore chants, when properly used, magnetize the Presence, whether universal or individualized, of the Divine Consciousness.
Mark L. Prophet and Elizabeth Clare Prophet, The Science of the Spoken Word
