You will understand the difference and distinction between physical-sense
telepathy, and astral-sense telepathy, if you will carefully consider the
nature of each, as I shall now present it to you. I ask your close
attention to what I shall have to say on this subject in the remaining
pages of this chapter. Do not pass over these explanations as "dry," for
unless you have a clear fundamental understanding of the thing, you will
never be able to get the best results. This is true of every phase of
learning, physical as well as psychical--one must get started right, in

the natural fact that every manifestation of mental or emotional activity
is the result of an action of the brain or nervous system, manifesting in
a form of vibrations. Just as in the case of the manifestation of
electricity in which certain chemical elements are consumed, or
transformed, so in the case of mental or emotional activity there is a
consuming or transformation of the substance of which the nervous system
is composed. When I say "nervous system" in this connection, I include the
brain, or brains of man--for these are but a part of his great nervous

Nature's processes--all seeming destruction being but a transformation--so

the thought or emotional process. We may grasp this idea more clearly if
we consider what takes place into transformation of electrical energy. For
