theologians have been accustomed to conceive Divine Reality: that is to say, the so-called “emanation-theory” and “immanence-theory” of the transcendental world.
Emanation and Immanence are formidable words; which though perpetually tossed to and fro by amateurs of religious philosophy, have probably, as they stand, little actuality for practical modern men. They are, however, root-ideas for the maker of mystical diagrams: and his best systems are but attempts towards their reconciliation. Since the aim of every mystic is union with God, it is obvious that the vital question in his philosophy must be the place which this God, the Absolute of his quest, occupies in the scheme. Briefly, He has been conceived — or, it were better to say, presented — by the great mystics under two apparently contradictory modes.
(1) The opinion which is represented in its most extreme form by the theory of Emanations, declares His utter transcendence. This view appears early in the history of Greek philosophy. It is developed by Dionysius, by the Kabalists, by Dante: and is implied in the language of Rulman Merswin, St. John of the Cross and many other Christian ecstatics.
The solar system is an almost perfect symbol of this concept of Reality; which finds at once its most rigid and most beautiful expression in Dante’s “Paradiso.”182 The Absolute Godhead is conceived as removed by a vast distance from the material world of sense; the last or lowest of that system of dependent worlds or states which, generated by or emanating from the Unity or Central Sun, become less in spirituality and splendour, greater in multiplicity, the further they recede from their source. That Source — the Great Countenance of the Godhead — can never, say the Kabalists, be discerned by man. It is the Absolute of the Neoplatonists, the Unplumbed Abyss of later mysticism: the Cloud of Unknowing wraps it from our sight. Only by its “emanations” or manifested attributes can we attain knowledge of it. By the outflow of these same manifested attributes and powers the created universe exists, depending in the last resort on the latens Deitas: Who is therefore conceived as external to the world which He illuminates and vivifies.
St. Thomas Aquinas virtually accepts the doctrine of Emanations when he writes:183 “As all the perfections of Creatures descend in order from God, who is the height of perfection, man should begin from the lower creatures and ascend by degrees, and so advance to the knowledge of God. . . . And because in that roof and crown of all things, God, we find the most perfect unity, and everything is stronger and more excellent the more thoroughly it is one; it follows that diversity and variety increase in things, the further they are removed from Him who is the first principle of all.” Suso, whose mystical system, like that of most Dominicans, is entirely consistent with Thomist philosophy, is really glossing Aquinas when he writes: “The supreme and superessential Spirit has ennobled man by illuminating him with a ray from the Eternal Godhead. . . . Hence from out the great ring which represents the Eternal Godhead there flow forth . . . little rings, which may be taken to signify the high nobility of natural creatures.”184
Obviously, if this theory of the Absolute be accepted the path of the soul’s ascent to union with the divine must be literally a transcendence: a journey “upward and outward,” through a long series of intermediate states or worlds till, having traversed the “Thirty-two paths of the Tree of Life,” she at last arrives, in Kabalistic language, at the Crown: fruitive knowledge of God, the Abyss or Divine Dark of the Dionysian school, the Neoplatonic One. Such a series of worlds is symbolized by the Ten Heavens of Dante, the hierarchies of Dionysius, the Tree of Life or Sephiroth of the Kabalah: and receives its countersign in the inward experience, in the long journey of the self through Purgation and Illumination to Union. “We ascend,” says St. Augustine, “thy ways that be in our heart, and sing a song of degrees; we glow inwardly with thy fire, with thy good fire, and we go, because we go upwards to the peace of Jerusalem.”185
This theory postulates, under normal and non-mystical conditions, the complete separation of the human and the divine; the temporal and the eternal worlds. “Never forget,” says St. John of the Cross, “that God is inaccessible. Ask not therefore how far your powers may comprehend Him, your feeling penetrate Him. Fear thus to content yourself with too little, and deprive your soul of the agility which it needs in order to mount up to Him.”186 The language of pilgrimage, of exile, comes naturally to the mystic who apprehends reality under these terms. To him the mystical adventure is essentially a “going forth” from his normal self and from his normal universe. Like the Psalmist “in his heart he hath disposed to ascend by steps in this vale of tears” from the less to the more divine. He, and with him the Cosmos — for to mystical philosophy the soul of the individual subject is the microcosm of the soul of the world — has got to retrace the long road to the Perfection from which it originally came forth; as the fish in Rulman Merswin’s Vision of Nine Rocks must struggle upwards from pool to pool until they reach their Origin.
Such a way of conceiving Reality accords with the type of mind which William James called the “sick soul.”187 It is the mood of the penitent; of the utter humility which, appalled by the sharp contrast between itself and the Perfect which it contemplates, can only cry “out of the depths.” It comes naturally to the temperament which leans to pessimism, which sees a “great gulf fixed” between itself and its desire, and is above all things sensitive to the elements of evil and imperfection in its own character and in the normal experience of man. Permitting these elements to dominate its field of consciousness, wholly ignoring the divine aspect of the World of Becoming, such a temperament constructs from its perceptions and prejudices the concept of a material world and a normal self which are very far from God.
(2) Immanence. At the opposite pole from this way of sketching Reality is the extreme theory of Immanence, which plays so large a part in modern theology. To the holders of this theory, who commonly belong to James’s “healthy minded” or optimistic class, the quest of the Absolute is no long journey, but a realization of something which is implicit in the self and in the universe: an opening of the eyes of the soul upon the Reality in which it is bathed. For them earth is literally “crammed with heaven.” “Thou wert I, but dark was my heart, I knew not the secret transcendent,” says Téwekkul Bég, a Moslem mystic of the seventeenth century.188 This is always the cry of the temperament which leans to a theology of immanence, once its eyes are opened on the light. “God,” says Plotinus, “is not external to anyone, but is present with all things, though they are ignorant that He is so.”189 In other and older words, “The Spirit of God is within you.” The Absolute Whom all seek does not hold Himself aloof from an imperfect material universe, but dwells within the flux of things: stands as it were at the very threshold of consciousness and knocks awaiting the self’s slow discovery of her treasures. “He is not far from any one of us, for in Him we live and move and have our being,” is the pure doctrine of Immanence: a doctrine whose teachers are drawn from amongst the souls which react more easily to the touch of the Divine than to the sense of alienation and of sin, and are naturally inclined to love rather than to awe.
Unless safeguarded by limiting dogmas, the theory of Immanence, taken alone, is notoriously apt to degenerate into pantheism; and into those extravagant perversions of the doctrine of “deification” in which the mystic holds his transfigured self to be identical with the Indwelling God. It is the philosophical basis of that practice of introversion, the turning inward of the soul’s faculties in contemplation, which has been the “method” of the great practical mystics of all creeds. That God, since He is in all — in a sense, is all — may most easily be found within ourselves, is the doctrine of these adventurers;190 who, denying or ignoring the existence of those intervening “worlds” or “planes” between the material world and the Absolute, which are postulated by the theory of Emanations, claim with Ruysbroeck that “by a simple introspection in fruitive love” they “meet God without intermediary.”191 They hear the Father of Lights “saying eternally, without intermediary or interruption, in the most secret part of the spirit, the one, unique, and abysmal Word.”192
This discovery of a “divine” essence or substance, dwelling, as Ruysbroeck says, at the apex of man’s soul is that fundamental experience — found in some form or degree in all genuine mystical religion — which provides the basis of the New Testament doctrine of the indwelling spirit. It is, variously interpreted, the “spark of the soul” of Eckhart, the “ground” of Tauler, the Inward Light of
