But this growth into higher realities, this blossoming of your contemplative consciousness--though it be, like all else we know in life, an unbroken process of movement and change--must be broken up and reduced to the series of concrete forms which we call "order" if our inelastic minds are to grasp it. So, we will consider it as the successive achievement of those three levels or manifestations of Reality, which we have agreed to call the Natural World of Becoming, the Metaphysical World of Being, and--last and highest--that Divine Reality within which these opposites are found as one. Though these three worlds of experience are so plaited together, that intimations from the deeper layers of being constantly reach you through the natural scene, it is in this order of realisation that you may best think of them, and of your own gradual upgrowth to the full stature of humanity. To elude nature, to refuse her friendship, and attempt to leap the river of life in the hope of finding God on the other side, is the common error of a perverted mysticality. It is as fatal in result as the opposite error of deliberately arrested development, which, being attuned to the wonderful rhythms of natural life, is content with this increase of sensibility; and, becoming a "nature-mystic," asks no more. So you are to begin with that first form of contemplation which the old mystics sometimes called the "discovery of God in His creatures." Not with some ecstatic adventure in supersensuous regions, but with the loving and patient exploration of the world that lies at your gates; the "ebb and flow and ever-during power" of which your own existence forms a part. You are to push back the self's barriers bit by bit, till at last all duration is included in the widening circles of its intuitive love: till you find in every manifestation of life--even those which you have petulantly classified as cruel or obscene--the ardent self-expression of that Immanent Being whose spark burns deep in your own soul.
