lack knowledge of much that is true, regarding
Nature, her realm and her laws.

An Appeal To Reason.

Concluding these statements, let us say that the student of this book
will find nothing contained within this book which is contrary to
Nature's laws and principles. He will nowhere in it be asked to suspend
the exercise of his reason, and to accept as facts things which violate
all of Nature's laws. Instead, he will find at each point full natural
explanations of even the most wonderful phenomena; and the appeal to
accept same will be made always to his reason, and not to his blind
faith or unreasoning belief. The student is urged to build his knowledge
of this important subject upon this solid rock of natural law and fact,
and not upon the shifting and sinking sands of mere dogmatic assertion
and appeal to assumed authority ancient or modern.

PART II

Mental Vibrations and Transmissions

In the category of Nature's Finer Forces must be included that class of
manifestations which are generally known as Telepathy, Thought
Transference, Thought Force, etc., all of which are based upon the fact
that there is present in all such mental states as Thought, Emotion,
Desire, etc., a certain rate of vibratory motion, which motion is
capable of being radiated from the mind of the person manifesting them
in such power and force that they may be registered with more or less
distinctness upon the minds of other persons are at a greater or less
distance from the first person. In the more common forms of its
manifestation, such mental force or power is known as Thought Force,
Mental Influence, etc., and in its more pronounced and less common
phases it is known as Telepathy, Thought Transference, etc., but the
basic principle is precisely the same in all of such cases, simple or
complex though their manifestations may be.

The Higher Forces.

We may say here, frankly and plainly, however, that the advanced
occultists regard this class of phenomena as comparatively simple and
elementary, and therefore not fully entitled to be included in the same
category with the higher phases of Nature's Finer Forces, such as, for
instance, Clairvoyance, Psychometry, Communication with the Higher
Planes, etc. But notwithstanding this, we are of the opinion that any
and every one of the finer forces of nature, i.e., any of the forces
which are over and above the plane upon which the ordinary senses of
man, normally developed, ord
