The silent mind, cultivated in many different forms of meditation, is the matrix of intuition. When you are in touch with the stillpoint at the center of your being there is no need to use imagery or verbal exercises to activate intuition. It flows by itself, unimpeded by fears or preoccupations.
Prayer is a response to God and to live coming from a heart that has been touched. How does a heart touched by God pray? Sometimes in pure gratitude it simply stands in awe rejoicing. And that is prayer! Sometimes it weeps. Sometimes it sings. At times it talks tenderly to God. At other times it might scream out in anger and pain. Sometimes it looks on the world with love, or rushes out to do good deeds. Sometimes it kneels without-stretched arms. Sometimes it merely yearns for God in deep, holy silence. All this is prayer.
