A: The Primordial Sound Meditation technique originates from the ancient knowledge of India. Deepak Chopra and David Simon have revived this authentic process and made it available in a format that can be easily learned and practiced by everyone. It is an easily learned meditation technique which uses individually selected vibratory sounds, or mantras, to create a quieting influence in the mind. When used correctly, these mantras guide the awareness from the level of activity to the realm of silence.
