_Mr. Schonfeld:_ Sri Chinmoy, you also use a chant of some kind. What does that do?

Sri Chinmoy: I was chanting Aum at that time. Aum is the mother of all Indian incantations or mantras. I was invoking the three principal Indian Gods: Brahma, Vishnu and Shiva. Brahma is the Creator, Vishnu is the Preserver and Shiva is the Transformer. I was invoking these three cosmic gods to illumine our consciousness. As you know, God exists in three aspects: God the Creator, God the Preserver and God the Transformer. Aum has three sounds: a, u and m. When they are united, they become Aum.
