Those who neglect silence bring only a distracted heart and a preoccupied mind to their prayer and, instead of deriving new strength from it, they only offer God a heart full of trifles. Intimate conversation with God is easily stifled if you do not first put an end to exterior chatter; yet, if you love silence and keep it well, your heart will be a temple where God will dwell and become known to you there.
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.
