can think, say, or do, may (in virtue of that historical incarnation) be justly called the indwelling Christ. This is all that the Christian mystic needs. Sect. 10. SPECIMENS OF MODERN MYSTICISM I conclude this introductory essay with a few extracts from recent American books on the psychology of religion. It is interesting to find some of the strangest experiences of the cloister reproduced under the very different conditions of modern American life. The quotations will serve to show how far Tauler and the "Theologia Germanica" are from being out of date. "The thing which impressed me most" (says a correspondent of Professor William James)[33] "was learning the fact that we must be in absolutely constant relation or mental touch with that essence of life which permeates all and which we call God. This is almost unrecognisable unless we live into it ourselves actually--that is, by a constant turning to the very innermost, deepest consciousness of our real selves or of God in us, for illumination from within, just as we turn to the sun for light, warmth, and invigoration without. When you do this consciously, realising that to turn inward to the light within you is to live in the presence of God or of your Divine self, you soon discover the unreality of the objects to which you have hitherto been turning and which have engrossed you without." The next quotation comes from a small book by one of the "New Thought" or "Mind Cure" school in America. The enormous sale of the volume testifies to the popularity of the teaching which it contains.[34]
