Now the artist, the discoverer, the philosopher, the lover, the patriot--the true enthusiast for any form of life--can only achieve the full reality to which his special art or passion gives access by innumerable renunciations. He must kill out the smaller centres of interest, in order that his whole will, love, and attention may pour itself out towards, seize upon, unite with, that special manifestation of the beauty and significance of the universe to which he is drawn. So, too, a deliberate self-simplification, a "purgation" of the heart and will, is demanded of those who would develop the form of consciousness called "mystical." All your power, all your resolution, is needed if you are to succeed in this adventure: there must be no frittering of energy, no mixture of motives. We hear much of the mystical temperament, the mystical vision. The mystical character is far more important: and its chief ingredients are courage, singleness of heart, and self-control. It is towards the perfecting of these military virtues, not to the production of a pious softness, that the discipline of asceticism is largely directed; and the ascetic foundation, in one form or another, is the only enduring foundation of a sane contemplative life. You cannot, until you have steadied yourself, found a poise, and begun to resist some amongst the innumerable claims which the world of appearance perpetually makes upon your attention and your desire, make much use of the new power which Recollection has disclosed to you; and this Recollection itself, so long as it remains merely a matter of attention and does not involve the heart, is no better than a psychic trick. You are committed therefore, as the fruit of your first attempts at self-knowledge, to a deliberate--probably a difficult--rearrangement of your character; to the stern course of self-discipline, the voluntary acts of choice on the one hand and of rejection on the other, which ascetic writers describe under the formidable names of Detachment and Mortification. By Detachment they mean the eviction of the limpet from its crevice; the refusal to anchor yourself to material things, to regard existence from the personal standpoint, or confuse custom with necessity. By Mortification, they mean the resolving of the turbulent whirlpools and currents of your own conflicting passions, interests, desires; the killing out of all those tendencies which the peaceful vision of Recollection would condemn, and which create the fundamental opposition between your interior and exterior life.
