“Books are those faithful mirrors that reflect to our mind the minds of sages and heroes.”

Context: Holy Scripture presents a kind of mirror to the eyes of the mind, so that our inner face may be seen in it. There we learn our own ugliness, there our own beauty.

The Saviors of God (1923)
Context: All this world, all this rich, endless flow of appearances is not a deception, a multicolored phantasmagoria of our mirroring mind. Nor is it absolute reality which lives and evolves freely, independent of our mind's power.
It is not the resplendent robe which arrays the mystic body of God. Nor the obscurely translucent partition between man and mystery.
All this world that we see, hear, and touch is that accessible to the human senses, a condensation of the two enormous powers of the Universe permeated with all of God.

Original: (la) Scriptura sacra mentis oculis quasi quoddam speculum opponitur, ut interna nostra facies in ipsa videatur. Ibi etenim foeda, ibi pulchra nostra cognoscimus.
