Blessing is an attitude toward all of life, transcending and moving beyond words. When family and friends gather around a table to break bread together, this is a blessing. When we harden our hearts against anyone, this is a cursing.
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.
