Our word "courage" comes form the French word coeur, "heart." Courage is a willingness to act from the heart, to let your heart lead the way, not knowing what will be required of you next, and if you can do it.
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.
