I saw the massive stone altar first begin to glow like a ruby; then it was a heart of liquid gold like a solid single-crystal chrysoprase: the gold intensified into ice-cold emerald and passed into the dark sapphire of an arctic sky; this again withdrew into a violet so deep that the visual purple of the eye itself seemed absorbed in that depth, that abyss of color in which sight was being drowned. And as this intensification of vibrancy seemed to sweep across the visible spectrum up to those ranges where energy absorbs all mass and that which can pierce the most solid is itself fine beyond all substance, so it seemed with hearing. That abyss of sound which I had been thinking of as only depth, it, too, seemed to rise or, rather, I suppose I was carried up on some rising wave which explored the deep of the height.As the light drew toward the invisible, I experienced a sound so acute that I can only remember feeling to myself that this was the note emitted when the visible universe returns to the unmanifest—this was the consummatum est of creation. I knew that an aperture was opening in the solid manifold. The things of sense were passing with the music of their own transmutation, out of sight. Veil after veil was evaporating under the blaze of the final Radiance. Suddenly I knew terror as never before. The only words which will go near to recreating in me some hint of that actual mode are those which feebly point toward the periphery of panic by saying that all things men dread are made actually friendly by this ultimate awfulness. Every human horror, every evil that the physical body may suffer, seemed, beside this that loomed before me, friendly, homely, safe. The rage of a leaping tiger would have been a warm embrace. The hell of a forest wrapped in a hurricane of fire, the subzero desolation of the antarctic blizzard, would have been only the familiar motions of a simple well-known world. Yes, even the worst, most cunning and cruel evil would only be the normal reassuring behavior of a well-understood, much-sympathized-with child. Against This, the ultimate Absolute, how friendly became anything less, anything relative.
