Strictly speaking, words play no part at all in healing. The motivating factor is prayer, or asking. What you ask for you receive. But this refers to the prayer of the heart, not to the words you use in praying. Sometimes the words and the prayer are contradictory; sometimes they agree. It does not matter. God does not understand words, for they were made by separated minds to keep them in the illusion of separation. Words can be helpful, particularly for the beginner, in helping concentration and facilitating the exclusion, or at least the control, of extraneous thoughts. Let us not forget, however, that words are but symbols of symbols. They are thus twice removed from reality. 

As symbols, words have quite specific references. Even when they seem most abstract, the picture that comes to mind is apt to be very concrete. Unless a specific referent does occur to the mind in conjunction with the word, the word has little or no practical meaning, and thus cannot help the healing process. The prayer of the heart does not really ask for concrete things. It always requests some kind of experience, the specific things asked for being the bringers of the desired experience in the opinion of the asker. The words, then, are symbols for the things asked for, but the things themselves but stand for the experiences that are hoped for.

The prayer for things of this world will bring experiences of this world. If the prayer of the heart asks for this, this will be given because this will be received. It is impossible that the prayer of the heart remain unanswered in the perception of the one who asks. If he asks for the impossible, if he wants what does not exist or seeks for illusions in his heart, all this becomes his own. The power of his decision offers it to him as here quests. Herein lie hell and Heaven. The sleeping Son of God has but this power left to him. It is enough. His words do not matter. Only the Word of God has any meaning, because it symbolizes that which has no human symbols at all. The Holy Spirit alone understands what this Word stands for. And this, too, is enough.
