The education of the mystical sense begins in self-simplification. The feeling, willing, seeing self is to move from the various and the analytic to the simple and the synthetic: a sentence which may cause hard breathing and mopping of the brows on the part of the practical man. Yet it is to you, practical man, reading these pages as you rush through the tube to the practical work of rearranging unimportant fragments of your universe, that this message so needed by your time--or rather, by your want of time-- is addressed. To you, unconscious analyst, so busy reading the advertisements upon the carriage wall, that you hardly observe the stages of your unceasing flight: so anxiously acquisitive of the crumbs that you never lift your eyes to the loaf. The essence of mystical contemplation is summed in these two experiences-- union with the flux of life, and union with the Whole in which all lesser realities are resumed--and these experiences are well within your reach. Though it is likely that the accusation will annoy you, you are already in fact a potential contemplative: for this act, as St. Thomas Aquinas taught, is proper to all men--is, indeed, the characteristic human activity. More, it is probable that you are, or have been, an actual contemplative too. Has it never happened to you to lose yourself for a moment in a swift and satisfying experience for which you found no name? When the world took on a strangeness, and you rushed out to meet it, in a mood at once exultant and ashamed? Was there not an instant when you took the lady who now orders your dinner into your arms, and she suddenly interpreted to you the whole of the universe? a universe so great, charged with so terrible an intensity, that you have hardly dared to think of it since. Do you remember that horrid moment at the concert, when you became wholly unaware of your comfortable seven-and-sixpenny seat? Those were onsets of involuntary contemplation; sudden partings of the conceptual veil. Dare you call them the least significant, moments of your life? Did you not then, like the African saint, "thrill with love and dread," though you were not provided with a label for that which you adored?
