al Plane, in Mental
Transmutation. In fact all that we call "psychic phenomena,"; "mental
influence"; "mental science"; "new-thought phenomena," etc., operates
along the same general lines, for there is but one principle involved,
no matter by what name the phenomena be called.

The student and practitioner of Mental Transmutation works among the
Mental Plane, transmuting mental conditions, states, etc., into others,
according to various formulas, more or less efficacious. The various
"treatments," "affirmations," "denials" etc., of the schools of mental
science are but formulas, often quite imperfect and unscientific, of The
Hermetic Art. The majority of modern practitioners are quite ignorant
compared to the ancient masters, for they lack the fundamental knowledge
upon which the work is based.

Not only may the mental states, etc., of one's self be changed or
transmuted by Hermetic Methods; but also the states of others may be,
and are, constantly transmuted in the same way, usually unconsciously,
but often consciously by some understanding the laws and principles, in
cases where the people affected are not informed of the principles of
self-protection. And more than this, as many students and practitioners
of modern mental science know, every material condition depending upon
the minds of other people may be changed or transmuted in accordance
with the earnest desire, will, and "treatments" of person desiring
changed conditions of life. The public are so generally informed
regarding these things at present, that we do not deem it necessary to
mention the same at length, our purpose at this point being merely to
show the Hermetic Principle and Art underlying all of these various
forms of practice, good and evil, for the force can be used in opposite
directions according to the Hermetic Principles of Polarity.

In this little book we shall state the basic principles of Mental
Transmutation, that all who read may grasp the Underlying Principles,
and thus possess the Master-Key that will unlock the many doors of the
Principle of Polarity.

We shall now proceed to a consideration of the first of the Hermetic
Seven Principles--the Principle of Mentalism, in which is explained the
truth that "THE ALL is Mind; the Universe is Mental," in the words of
The Kybalion. We ask the close attention, and careful study of this
great Principle, on the part of our students, for it is really the Basic
Principle of the whole Hermetic
