The empirical mind relies upon the spirit and method of science, wanting to test propositions for their truth, and respecting that which will work. This intuitionist way is often called the way of the mystic. In actuality, however, the mystical signifies something quite different in human response. It means the belief that the truth of things can be apprehended directly and immediately, that is, without the mediation of the ordinary senses. The mystical has been an element in all the great religions in the world, and vigorous mystical strains are found in each of them, creating distinct groups of followers.
Mysticism holds a place of honor and significance in religion.
The frequency with which the mystical element appears, both within and outside the religions, constitutes the mystic way as one of the perennial philosophies of life. It may even be affirmed that no human being on earth has not had at some time, in some degree or in some form, an experience with an element of the mystical in it. Throughout history, the more dramatic and extreme occurrences of this kind have been given the name of mystical, while milder and more moderate feelings of this sort have been considered a part of normal existence, not especially mystical or even religious. Such natural incidents come in a wide variety of forms. Common to all of them is the awareness that life is larger, or deeper, or more mysterious than it usually seems.
