Because some kinds of mystical experience are clothed in forms which are really projections of ordinary all-too-human feelings, the materialist rejects the whole experience as being a fantasy. He tears it to pieces by his criticism and imagines he has satisfactorily disposed of the subject. But he fails to account for that part of it which is the deepest and least human, the holiest and least ordinary, the truest and least imaginary. He fails to account for the message which every genuine mystic receives when standing on this sacred ground: that here is the ultimate significance of all experience, including everyday experience.
