of a
transmutation of one thing into another thing entirely different-but is
merely a change of degree in the same things, a vastly important
difference. For instance, borrowing an analogy from the Physical Plane,
it is impossible to change Heat into Sharpness, Loudness, Highness,
etc., but Heat may readily be transmuted into Cold, simply by lowering
the vibrations. In the same way Hate and Love are mutually transmutable;
so are Fear and Courage. But Fear cannot be transformed into Love, nor
can Courage be transmuted into Hate. The mental states belong to
innumerable classes, each class of which has its opposite poles, along
which transmutation is possible.

The student will readily recognize that in the mental states, as well as
in the phenomena of the Physical Plane, the two poles may be classified
as Positive and Negative, respectively. Thus Love is Positive to Hate;
Courage to Fear; Activity to Non-Activity, etc., etc. And it will also
be noticed that even to those unfamiliar with the Principle of
Vibration, the Positive pole seems to be of a higher degree than the
Negative, and readily dominates it. The tendency of Nature is in the
direction of the dominant activity of the Positive pole.

In addition to the changing of the poles of one's own mental states by
the operation of the art of Polarization, the phenomena of Mental
Influence, in its manifold phases, shows us that the principle may be
extended so as to embrace the phenomena of the influence of one mind
over that of another, of which so much has been written and taught of
late years. When it is understood that Mental Induction is possible,
that is that mental states may be produced by "induction" from others,
then we can readily see how a certain rate of vibration, or polarization
of a certain mental state, may be communicated to another person, and
his polarity in that class of mental states thus changed. It is along
this principle that the results of many of the "mental treatments" are
obtained. For instance, a person is "blue," melancholy and full of fear.
A mental scientist bringing his own mind up to the desired vibration by
his trained will, and thus obtaining the desired polarization in his own
case, then produces a similar mental state in the other by induction,
the result being that the vibrations are raised and the person polarizes
toward the Positive end of the scale instead toward the Negative, and
his Fear and other negative emotions are transmu
