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 transmuted to Courage and
similar positive mental states. A little study will show you that these
mental changes are nearly all along the line of Polarization, the change
being one of degree rather than of kind.

A knowledge of the existence of this great Hermetic Principle will
enable the student to better understand his own mental states, and those
of other people. He will see that these states are all matters of
degree, and seeing thus, he will be able to raise or lower the vibration
at will--to change his mental poles, and thus be Master of his mental
states, instead of being their servant and slave. And by his knowledge
he will be able to aid his fellows intelligently and by the appropriate
methods change the polarity when the same is desirable. We advise all
students to familiarize themselves with this Principle of Polarity, for
a correct understanding of the same will throw light on many difficult
subjects.
