Because mystery is horrible to us, we have agreed for the most part to live in a world of labels; to make of them the current coin of experience, and ignore their merely symbolic character, the infinite gradation of values which they misrepresent. We simply do not attempt to unite with Reality. But now and then that symbolic character is suddenly brought home to us. Some great emotion, some devastating visitation of beauty, love, or pain, lifts us to another level of consciousness; and we are aware for a moment of the difference between the neat collection of discrete objects and experiences which we call the world, and the height, the depth, the breadth of that living, growing, changing Fact, of which thought, life, and energy are parts, and in which we “live and move and have our being.” Then we realise that our whole life is enmeshed in great and living forces; terrible because unknown.
The more sacred plane of life and energy which seems to be manifested in the forces we call “spiritual” and “emotional”–in love, anguish, ecstasy, adoration–is hidden from us too. Symptoms, appearances, are all that our intellects can discern: sudden irresistible inroads from it, all that our hearts can apprehend.
As a tapestry picture, however various and full of meaning, is ultimately reducible to little squares; so the world of common sense is ultimately reducible to a series of static elements conditioned by the machinery of the brain. Subtle curves, swift movement, delicate gradation, that machinery cannot represent. It leaves them out. From the countless suggestions, the tangle of many-coloured wools which the real world presents to you, you snatch one here and there. Of these you weave together those which are the most useful, the most obvious, the most often repeated: which make a tidy and coherent pattern when seen on the right side. Shut up with this symbolic picture, you soon drop into the habit of behaving to it as though it were not a representation but a thing. On it you fix your attention; with it you “unite.”

But the doors of perception are hung with the cobwebs of thought; prejudice, cowardice, sloth. Eternity is with us, inviting our contemplation perpetually, but we are too frightened, lazy, and suspicious to respond: too arrogant to still our thought, and let divine sensation have its way. It needs industry and goodwill if we would make that transition: for the process involves a veritable spring-cleaning of the soul, a turning-out and rearrangement of our mental furniture, a wide opening of closed windows, that the notes of the wild birds beyond our garden may come to us fully charged with wonder and freshness, and drown with their music the noise of the gramaphone within. Those who do this, discover that they have lived in a stuffy world, whilst their inheritance was a world of morning-glory; where every tit-mouse is a celestial messenger, and every thrusting bud is charged with the full significance of life.

Our vision and understanding of it are governed by all that we bring with us, and mix with it, to form an amalgam with which the mind can deal. To “purify” the senses is to release them, so far as human beings may, from the tyranny of egocentric judgments; to make of them the organs of direct perception. This means that we must crush our deep-seated passion for classification and correspondences; ignore the instinctive, selfish question, “What does it mean to me?” learn to dip ourselves in the universe at our gates, and know it, not from without by comprehension, but from within by self-mergence.
