But concentration has an even greater significance than this, for it is that creative power which man possesses and which he has as a heritage of God. That creative power begins to work wonders. For instance, a person thinks, "I should like fish for dinner", and when he comes home he finds that his housekeeper has cooked fish that evening. That is a phenomenon of concentration. He may not know it, but it worked in that way. The thought of the man struck the mind of the housekeeper, and the housekeeper served that dish to him. Imagine what a great power this is! One need not even think about one's desires; the very fact of having the desire is enough; concentration works it out and materializes it.
