SCIENCE OF BEING AND ART OF LIVING TRANSCENDENTAL MEDITATIONBy Maharashi Mahesh Yogi (Osho)

We know that power is greater in the subtle strata of creation than in the gross. If we throw a stone at someone it will hurt him, but if we could enter into its subtle strata and excite an atom of the stone, tremendous energy would be released, and the effect would be far greater. Similarly, when we enter into the subtler states of a thought, we appreciate its finer levels, and the power is much greater than it would be on the common conscious level of the mind. With this in view, it is essential that, before starting the practice of Transcendental Meditation, a proper quality of sound should be selected.
