Mysticism in its noblest sense, mysticism as it existed in St John, and Plato, and Paracelsus, and Sir Thomas Browne, is not an exceptionally dark and secret thing, but an exceptionally luminous and open thing. It is in reality too clear for most of us to comprehend, and too obvious for most of us to see. Such an utterance as the utterance that “God is Love” does in reality overwhelm us like an immeasurable landscape on a clear day, like the light of an intolerable summer sun. We may call it a dark saying; but we have an inward knowledge all the time that it is we who are dark…
It is remarkable to notice even in daily life how constant is this impression of the essential rationality of mysticism. If we went up up to a man in the street who happened to be standing opposite a lamppost and addressed him playfully with the words, “Whence did this strange object spring? How did this lean Cyclops with the eye of fire start out of unbegotten night?” it may be generally inferred, with every possible allowance for the temperament of the individual, that he would not regard our remarks as particularly cogent and practical. And yet our surprise at the lamppost would be entirely rational; his habit of taking lampposts for granted would be merely a superstition. The power that makes men accept material phenomena of this universe, its cities, civilizations, and solar systems, is merely a vulgar prejudice, like the prejudice that made them accept cock-fights or the Inquisition. It is the mystic to whom every star is like a sudden rocket, every flower an earthquake of the dust, who is the clear-minded man.
Mysticism, or the sense of the mystery of things, is simply the most gigantic form of common-sense.
