Question: Guru, can the experience that AUM will give me be visual and auditory and will it bring me consciously closer to God?

Sri Chinmoy: Absolutely! It will do everything. It will be visible, it will be audible and it will bring you closer to God within you. AUM is the mother of all mantras. AUM is God's sound. Every second God is creating Himself anew inside AUM. This sound He used to create the world; this sound He uses to preserve the world; this sound He is using to transform the world.
