In Lessons X and XI, of the "Advanced Course" we called your attention to the Yogi teachings concerning Akasa or Matter, and showed you that all forms of what we know as Matter are but different forms of manifestation of the principle called Akasa, or as the Western scientists call it, "Ether." This Ether or Akasa is the finest, thinnest and most tenuous form of Matter, in fact it is Matter in its ultimate or fundamental form, the different forms of what we call Matter being but manifestations of this Akasa or Ether, the apparent difference resulting from different rates of vibration, etc. We mention this fact here merely to bring clearly before your mind the fact of the Universality of Matter, to the end that you may realize that each and every particle of your physical body is but a portion of this great principle of the Universe, fresh from the great store-house, and just about returning to it again, for the atoms of the body are constantly changing. That which appears as your flesh to-day, may have been part of a plant a few days before, and may be part of some other living thing a few days hence. Constant change is going on, and what is yours to-day was someone's else yesterday, and still another's to-morrow. You do not own one atom of matter personally, it is all a part of the common supply, the stream flowing through you and through all Life, on and on forever.
And so it is with the Vital Energy that you are using every moment of your life. You are constantly drawing upon the great Universal supply of Prana, then using what is given you, allowing the force to pass on to assume some other form. It is the property of all, and all you can do is to use what you need, and allow it to pass on. There is but one Force or Energy, and that is to be found everywhere at all times.
And even the great principle, Mind-substance, is under the same law. It is hard for us to realize this. We are so apt to think of our mental operations as distinctively our own—something that belongs to us personally—that it is difficult for us to realize that Mind-substance is a Universal principle just as Matter or Energy, and that we are but drawing upon the Universal supply in our mental operations. And more than this, the particular portion of Mind-substance that we are using, although separated from the Mind-substance used by other individuals by a thin wall of the very finest kind of Matter, is really in touch with the other apparently separated minds, and with the Universal Mind of which it forms a part. Just as is the Matter of which our physical bodies are composed really in touch with all Matter; and just as is the Vital Force used by us really in touch with all Energy; so is our Mind-substance really in touch with all Mind-substance. It is as if the Ego in its progress were moving through great oceans of Matter, Energy, or Mind-substance, making use of that of each which it needed and which immediately surrounded it, and leaving each behind as it moved on through the great volume of the ocean. This illustration is clumsy, but it may bring to your consciousness a realization that the Ego is the only thing that is really Yours, unchangeable and unaltered, and that all the rest is merely that portion of the Universal supply that you draw to yourself for the wants of the moment. It may also bring more clearly before your mind the great Unity of things—may enable you to see things as a Whole, rather than as separated parts. Remember, You—the "I"—are the only Real thing about and around you—all that has permanence—and Matter, Force and even Mind-substance, are but your instruments for use and expression. There are great oceans of each surrounding the "I" as it moves along.
It is well for you also to bear in mind the Universality of Life. All of the Universe is alive, vibrating and pulsating with life and energy and motion. There is nothing dead in the Universe. Life is everywhere, and always accompanied by intelligence. There is no such thing as a dead, unintelligent Universe. Instead of being atoms of Life floating in a sea of death, we are atoms of Life surrounded by an ocean of Life, pulsating, moving, thinking, living. Every atom of what we call Matter is alive. It has energy or force with it, and is always accompanied by intelligence and life. Look around us as we will—at the animal world—at the plant world—yes, even at the world of minerals and we see life, life, life—all alive and having intelligence. When we are able to bring this conception into the realm of actual consciousness—when we are able not only to intellectually accept this fact, but to even go still further and feel and be conscious of this Universal Life on all sides, then are we well on the road to attaining the Cosmic Consciousness.
But all these things are but steps leading up to the realization of the Oneness in Spirit, on the part of the Individual. Gradually there dawns upon him the realization that there is a Unity in the manifestation of Spirit from the Absolute—a unity with itself, and a Union with the Absolute. All this manifestation of Spirit on the part of the Absolute—all this begetting of Divine Children—was in the nature of a single act rather than as a series of acts, if we may be permitted to speak of the manifestation as an act. Each Ego is a Centre of Consciousness in this great ocean of Spirit—each is a Real Self, apparently separate from the others and from its source, but the separation is only apparent in both cases, for there is the closest bond of union between the Egos of the Universe of Universes—each is knit to the other in the closest bond of union, and each is still attached to the Absolute by spiritual filaments, if we may use the term. In time we shall grow more conscious of this mutual relationship, as the sheaths are outgrown and cast aside, and in the end we will be withdrawn into the Absolute—shall return to the Mansion of the Father.
It is of the highest importance to the developing soul to unfold into a realization of this relationship and unity, for when this conception is once fully established the soul is enabled to rise above certain of the lower planes, and is free from the operation of certain laws that bind the undeveloped soul. Therefore the Yogi teachers are constantly leading the Candidates toward this goal. First by this path, and then by that one, giving them different glimpses of the desired point, until finally the student finds a path best fitted for his feet, and he moves along straight to the mark, and throwing aside the confining bonds that have proved so irksome, he cries aloud for joy at his new found Freedom.
The following exercises and Mental Drills are intended to aid the Candidate in his work of growing into a realization of his relationship with the Whole of Life and Being.
MENTAL DRILL
(1) Read over what we have said in the "Advanced Course" regarding the principle known as Matter. Realize that all Matter is One at the last—that the real underlying substance of Matter is Akasa or Ether, and that all the varying forms evident to our senses are but modifications and grosser forms of that underlying principle. Realize that by known chemical processes all forms of Matter known to us, or rather all combinations resulting in "forms," may be resolved into their original elements, and that these elements are merely Akasa in different states of vibration. Let the idea of the Oneness of the visible Universe sink deeply into your mind, until it becomes fixed there. The erroneous conception of diversity in the material world must be replaced by the consciousness of Unity—Oneness, at the last, in spite of the appearance of variety and manifold forms. You must grow to see behind the world of forms of Matter, and see the great principle of Matter (Akasa or Ether) back of, within, and under it all. You must grow to feel this, as well as to intellectually see it.
(2) Meditate over the last mentioned truths, and then follow the matter still further. Read what we have said in the "Advanced Course" (Lesson XI) about the last analysis of Matter showing it fading away into Force or Energy until the dividing line is lost, and Matter merges into Energy or Force, showing them both to be but the same thing, Matter being a grosser form of Energy or Force. This idea should be impressed upon the understanding, in order that the complete edifice of the Knowing of the Oneness may be complete in all of its parts.
(3) Then read in the "Advanced Lessons" about Energy or Force, in the oneness underlying its various manifestations. Consider how one form of Energy may be transformed into another, and so on around the circle, the one principle producing the entire chain of appearances. Realize that the energy within you by which you move and act, is but one of the forms of this great Principle of Energy with which the Universe is filled, and that you may draw to you the required Energy from the great Universal supply. But above all endeavor to grasp the idea of the Oneness pervading the
