Dr. Thompson, above mentioned, has also said: "In writing this work I have been unable to arrange my knowledge of a subject for days and weeks, until I experienced a clearing up of my mind, when I took my pen and unhesitatingly wrote the result. I have best accomplished this by leading the (conscious) mind as far away as possible from the subject upon which I was writing." Prof. Barrett says: "The mysteriousness of our being is not confined to subtle physiological processes which we have in common with all animal life. There are higher and more capacious powers wrapped up in our human personality than are expressed even by what we know of consciousness, will, or reason. There are supernormal and transcendental powers of which, at present, we only catch occasional glimpses; and behind and beyond the supernormal there are fathomless abysses, the Divine ground of the soul; the ultimate reality of which our consciousness is but the reflection or faint perception. Into such lofty themes I do not propose to enter, they must be forever beyond the scope of human inquiry; nor is it possible within the limits of this paper to give any adequate conception of those mysterious regions of our complex personality, which are open to, and beginning to be disclosed by, scientific investigation." Rev. Dr. Andrew Murray has written: "Deeper down than where the soul with its consciousness can enter there is spirit matter linking man with God; and deeper down than the mind and feelings or will--in the unseen depths of the hidden life--there dwells the Spirit of God." This testimony is remarkable, coming from that source, for it corroborates and reiterates the Yogi teachings of the Indwelling Spirit Schofield has written: "Our conscious mind as compared with the unconscious mind, has been likened to the visible spectrum of the sun's rays, as compared to the invisible part which stretches indefinitely on either side. We know now that the chief part of heat comes from the ultra-red rays that show no light; and the main part of the chemical changes in the vegetable world are the results of the ultra-violet rays at the other end of the spectrum, which are equally invisible to the eye, and are recognized only by their potent effects. Indeed as these invisible rays extend indefinitely on both sides of the visible spectrum, so we may say that the mind includes not only the visible or conscious part, and what we have termed the sub-conscious, that which lies below the red line, but the supraconscious mind that lies at the other end--all those regions of higher soul and spirit life, of which we are only at times vaguely conscious, but which always exist, and link us on to eternal verities, on the one side, as surely as the sub-conscious mind links us to the body on the other."
