Listening has to do with awareness. Hearing is easy; listening is difficult. Few of us recognize that listening is an ability and not an instinct. As such, it is an act that has to be learned. To listen is to be sensitive to reality. Good listeners live in the moment and pay attention to what is going on in the here-and-now ... a listening that is beyond words.
There is no progress in prayer without progress in faith, a purification of faith. And this entails the removal of all the props which depend on human endeavor, human reasoning, signs and the rest. It is the naked faith which is a terrifying experience and yet is the meeting point ultimately between God and ourselves in the depth of our being. This experience of the purification of faith is not normally one which comes early in the spiritual life. We must learn to wait.
