With regular TM practice, Transcendental Consciousness becomes permanent, forming an underlying continuum that coexists with waking, dreaming, and sleeping. These three states continue to come and go as before. But the underlying continuum of pure consciousness is never broken. The experience of inner silence is never lost—the inner light of the Self is never extinguished.
This is a fifth state of consciousness, altogether different from waking, dreaming, sleeping, and Transcendental Consciousness
This fifth state Maharishi terms Cosmic Consciousness. Cosmic means all inclusive, all encompassing. In Cosmic Consciousness, the mind is fully expanded. The ocean of consciousness is awake to its depth.
