“I knew what a circle could do. Both eyes focus on it. It stamps itself out, like a dot. This, in turn, causes one's vision to spread, as in a mandala in Tantric art.”

Ch 29
A Canticle for Leibowitz (1959), Fiat Voluntas Tua
Context: He received the Wafer from her hand. She replaced the lid of the ciborium and set the vessel in a more protected spot under a jutting rock. She used no conventional gestures, but the reverence with which she had handled it convinced him of one thing: she sensed the Presence under the veils. She who could not yet use words nor understand them, had done what she had as if by direct instruction, in response to his attempt at conditional baptism. He tried to refocus his eyes to get another look at the face of this being, who by gestures alone had said to him: I do not need your first Sacrament, Man, but I am worthy to convey to you this Sacrament of Life. Now he knew what she was, and he sobbed faintly when he could not again force his eyes to focus on those cool, green, and untroubled eyes of one born free.

Stephen Hero (1944)
Context: Imagine my glimpses at that clock as the gropings of a spiritual eye which seeks to adjust its vision to an exact focus. The moment the focus is reached the object is epiphanised. It is just in this epiphany that I find the third, the supreme quality of beauty. … No esthetic theory, pursued Stephen relentlessly, is of any value which investigates with the aid of the lantern of tradition. What we symbolise in black the Chinaman may symbolise in yellow: each has his own tradition. Greek beauty laughs at Coptic beauty and the American Indian derides them both. It is almost impossible to reconcile all tradition whereas it is by no means impossible to find the justification of every form of beauty which has ever been adored on the earth by an examination into the mechanism of esthetic apprehension whether it be dressed in red, white, yellow or black. We have no reason for thinking that the Chinaman has a different system of digestion from that which we have though our diets are quite dissimilar. The apprehensive faculty must be scrutinised in action.
