producible by thought. These things, the psychology of the Yogis, as well as
the teachings regarding the Dynamics of Thought, belong to that part of the
philosophy known as “Raja Yoga,” which will be taken up in our next course
of lessons.
We wish to say here, however, that students must not mistake the brain or
the brain-matter for Mind-substance. The brain-matter is merely the material
or matter through which Mind-substance manifests itself. The student will
find it better to think of Mind-substance as a force, rather than as a form of
Matter. The word “substance” when used in connection with Mind, seems to
give the idea of a “material” substance or form of matter, which is far from
being a true idea of its nature. And yet, we cannot very well say “Mind-
Force,” for that would indicate either a combination of Mind and Force, or
that form of Force used by the Mind when in activity. Mind-substance is a
higher form of Energy, and remains, like Energy itself, in a quiet or passive
state in its essence. Only when aroused into Thought does it form a union
with active Force. Remember these points please.
Concluding this consideration of Mind-substance, we would say that it
is omnipresent, that is present everywhere, and like Energy and Matter (its
progeny) it cannot be changed, added to, or taken away from. Moreover, it
cannot be really divided or separated, although in appearance it may be.
That is, although the mind of each Ego or Soul represents so much Mindsubstance,
apparently separated from other Mind-substance by a thin wall
of the finest kind of matter, yet, in reality, each mind is in touch with other
separated minds, and with the Universal Mind, of which it forms a part. All
Mind-substance is not separated or expressed in the shape of individual
minds any more than is all Ether manifested in gross Matter, or all Energy
converted into Force or Motion.
We would also have you remember that there is no such thing as “dead”
matter, for all the Universe is alive. And every particle of Matter contains
Energy and Mind-substance. The Universe is a great big vibrating, thinking
thing, from atom to sun, although its “thinking” may vary from the faintest
