It will not help you to speak of these experiences as "mere emotion." Mere emotion then inducted you into a world which you recognised as more valid--in the highest sense, more rational-- than that in which you usually dwell: a world which had a wholeness, a meaning, which exceeded the sum of its parts. Mere emotion then brought you to your knees, made you at once proud and humble, showed you your place. It simplified and unified existence: it stripped off the little accidents and ornaments which perpetually deflect our vagrant attention, and gathered up the whole being of you into one state, which felt and knew a Reality that your intelligence could not comprehend. Such an emotion is the driving power of spirit, an august and ultimate thing: and this your innermost inhabitant felt it to be, whilst your eyes were open to the light. Now that simplifying act, which is the preliminary of all mystical experience, that gathering of the scattered bits of personality into the _one_ which is really you--into the "unity of your spirit," as the mystics say--the great forces of love, beauty, wonder, grief, may do for you now and again. These lift you perforce from the consideration of the details to the contemplation of the All: turn you from the tidy world of image to the ineffable world of fact. But they are fleeting and ungovernable experiences, descending with dreadful violence on the soul. Are you willing that your participation in Reality shall depend wholly on these incalculable visitations: on the sudden wind and rain that wash your windows, and let in the vision of the landscape at your gates? You can, if you like, keep those windows clear. You can, if you choose to turn your attention that way, learn to look out of them. These are the two great phases in the education of every contemplative: and they are called in the language of the mystics the purification of the senses and the purification of the will. Those who are so fortunate as to experience in one of its many forms the crisis which is called "conversion" are seized, as it seems to them, by some power stronger than themselves and turned perforce in the right direction. They find that this irresistible power has cleansed the windows of their homely coat of grime; and they look out, literally, upon a new heaven and new earth. The long quiet work of adjustment which others must undertake before any certitude rewards them is for these concentrated into one violent shattering and rearranging of the self, which can now begin its true career of correspondence with the Reality it has perceived. To persons of this type I do not address myself: but rather to the ordinary plodding scholar of life, who must reach the same goal by a more gradual road.
