"The waves surged forth again, and Carter knew that the BEING had heard. And now there poured from that limitless MIND a flood of knowledge and explanation which opened new vistas to the seeker, and prepared him for such a grasp of the cosmos as he had never hoped to possess. He was told how childish and limited is the notion of a tri-dimensional world, and what an infinity of directions there are besides the known directions of up-down, forward-backward, right-left. He was shewn the smallness and tinsel emptiness of the little gods of earth, with their petty, human interests and connexions—their hatreds, rages, loves, and vanities; their craving for praise and sacrifice, and their demands for faith contrary to reason and Nature.
While most of the impressions translated themselves to Carter as words, there were others to which other senses gave interpretation. Perhaps with eyes and perhaps with imagination he perceived that he was in a region of dimensions beyond those conceivable to the eye and brain of man. He saw now, in the brooding shadows of that which had been first a vortex of power and then an illimitable void, a sweep of creation that dizzied his senses. From some inconceivable vantage-point he looked upon prodigious forms whose multiple extensions transcended any conception of being, size, and boundaries which his mind had hitherto been able to hold, despite a lifetime of cryptical study. He began to understand dimly why there could exist at the same time the little boy Randolph Carter in the Arkham farmhouse in 1883, the misty form on the vaguely hexagonal pillar beyond the First Gate, the fragment now facing the PRESENCE in the limitless abyss, and all the other “Carters” his fancy or perception envisaged.
Then the waves increased in strength, and sought to improve his understanding, reconciling him to the multiform entity of which his present fragment was an infinitesimal part. They told him that every figure of space is but the result of the intersection by a plane of some corresponding figure of one more dimension—as a square is cut from a cube or a circle from a sphere. The cube and sphere, of three dimensions, are thus cut from corresponding forms of four dimensions that men know only through guesses and dreams; and these in turn are cut from forms of five dimensions, and so on up to the dizzy and reachless heights of archetypal infinity. The world of men and of the gods of men is merely an infinitesimal phase of an infinitesimal thing—the three-dimensional phase of that small wholeness reached by the First Gate, where ’Umr at-Tawil dictates dreams to the Ancient Ones. Though men hail it as reality and brand thoughts of its many-dimensioned original as unreality, it is in truth the very opposite. That which we call substance and reality is shadow and illusion, and that which we call shadow and illusion is substance and reality.
Time, the waves went on, is motionless, and without beginning or end. That it has motion, and is the cause of change, is an illusion. Indeed, it is itself really an illusion, for except to the narrow sight of beings in limited dimensions there are no such things as past, present, and future. Men think of time only because of what they call change, yet that too is illusion. All that was, and is, and is to be, exists simultaneously.
These revelations came with a godlike solemnity which left Carter unable to doubt. Even though they lay almost beyond his comprehension, he felt that they must be true in the light of that final cosmic reality which belies all local perspectives and narrow partial views; and he was familiar enough with profound speculations to be free from the bondage of local and partial conceptions. Had his whole quest not been based upon a faith in the unreality of the local and partial?
After an impressive pause the waves continued, saying that what the denizens of few-dimensioned zones call change is merely a function of their consciousness, which views the external world from various cosmic angles. As the shapes produced by the cutting of a cone seem to vary with the angles of cutting—being circle, ellipse, parabola, or hyperbola according to that angle, yet without any change in the cone itself—so do the local aspects of an unchanged and endless reality seem to change with the cosmic angle of regarding. To this variety of angles of consciousness the feeble beings of the inner worlds are slaves, since with rare exceptions they cannot learn to control them. Only a few students of forbidden things have gained inklings of this control, and have thereby conquered time and change. But the entities outside the Gates command all angles, and view the myriad parts of the cosmos in terms of fragmentary, change-involving perspective, or of the changeless totality beyond perspective, in accordance with their will.
As the waves paused again, Carter began to comprehend, vaguely and terrifiedly, the ultimate background of that riddle of lost individuality which had at first so horrified him. His intuition pieced together the fragments of revelation, and brought him closer and closer to a grasp of the secret. He understood that much of the frightful revelation would have come upon him—splitting up his ego amongst myriads of earthly counterparts—inside the First Gate, had not the magic of ’Umr at-Tawil kept it from him in order that he might use the Silver Key with precision for the Ultimate Gate’s opening. Anxious for clearer knowledge, he sent out waves of thought, asking more of the exact relationship between his various facets—the fragment now beyond the Ultimate Gate, the fragment still on the quasi-hexagonal pedestal beyond the First Gate, the boy of 1883, the man of 1928, the various ancestral beings who had formed his heritage and the bulwark of his ego, and the nameless denizens of the other aeons and other worlds which that first hideous flash of ultimate perception had identified with him. Slowly the waves of the BEING surged out in reply, trying to make plain what was almost beyond the reach of an earthly mind.
All descended lines of beings of the finite dimensions, continued the waves, and all stages of growth in each one of these beings, are merely manifestations of one archetypal and eternal being in the space outside dimensions. Each local being—son, father, grandfather, and so on—and each stage of individual being—infant, child, boy, young man, old man—is merely one of the infinite phases of that same archetypal and eternal being, caused by a variation in the angle of the consciousness-plane which cuts it. Randolph Carter at all ages; Randolph Carter and all his ancestors both human and pre-human, terrestrial and pre-terrestrial; all these were only phases of one ultimate, eternal “Carter” outside space and time—phantom projections differentiated only by the angle at which the plane of consciousness happened to cut the eternal archetype in each case.
A slight change of angle could turn the student of today into the child of yesterday; could turn Randolph Carter into that wizard Edmund Carter who fled from Salem to the hills behind Arkham in 1692, or that Pickman Carter who in the year 2169 would use strange means in repelling the Mongol hordes from Australia; could turn a human Carter into one of those earlier entities which had dwelt in primal Hyperborea and worshipped black, plastic Tsathoggua after flying down from Kythanil, the double planet that once revolved around Arcturus; could turn a terrestrial Carter to a remotely ancestral and doubtfully shaped dweller on Kythanil itself, or a still remoter creature of trans-galactic Shonhi, or a four-dimensioned gaseous consciousness in an older space-time continuum, or a vegetable brain of the future on a dark radio-active comet of inconceivable orbit—and so on, in the endless cosmic circle.
The archetypes, throbbed the waves, are the people of the ultimate abyss—formless, ineffable, and guessed at only by rare dreamers on the low-dimensioned worlds. Chief among such was this informing BEING itself . . . which indeed was Carter’s own archetype. The glutless zeal of Carter and all his forbears for forbidden cosmic secrets was a natural result of derivation from the SUPREME ARCHETYPE. On every world all great wizards, all great thinkers, all great artists, are facets of IT."
