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 can not 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 eons 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.
