Meditation is basically the practice of quieting the mind on deeper and deeper levels until we reach the underlying, subtle consciousness that is the root of all things. But a quiet mind does not mean the absence of thoughts. It means a mind that does not interfere with or distort the natural flow of sensations, feelings, perceptions, images, and thoughts through the open field of our consciousness. A quiet mind is a clear space, a mirror for the entire experience of inner and outer life.
