ty 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 world of Energy or Force, or Motion. See it in its entirety, rather
than in its apparent separateness. These steps may appear somewhat
tedious and useless, but take our word for it, they are all helps in
fitting the mind to grasp the idea of the Oneness of All. Each step is
important, and renders the next higher one more easily attained. In this
mental drill, it will be well to mentally picture the Universe in
perpetual motion--everything is in motion--all matter is moving and
changing its forms, and manifesting the Energy within it. Suns and worlds
rush through space, their particles constantly changing and moving.
Chemical composition and decomposition is constant and unceasing,
everywhere the work of building up and breaking down is going on. New
combinations of atoms and worlds are constantly being formed and
dissolved. And after considering this Oneness of the principle of Energy,
reflect that through all these changes of form the Ego--the Real
Self--YOU--stand unchanged and unharmed--Eternal, Invincible,
Indestructible, Invulnerable, _Real_ and Constant among this changing
