eliefs, and interest, and to reject those which are opposed thereto.

Moreover, the person who acquaints himself with the law of mental
vibrations and thought-transference acquires a practical knowledge which
enables him to render himself immune to objectionable and undesirable
mental currents or thought-waves. We are not necessarily open to the
influence of every stray current of thought or feeling that happens to
be in our immediate vicinity. Instead, by the proper methods,
consciously or unconsciously practiced and manifested, we may, and often
do, insulate ourselves so that these undesirable mental influences fail
utterly to affect us; and, likewise, we may actually attract to
ourselves the desirable mental currents. These principles and methods
will be given later in this part of this book; they are mentioned here
merely to acquaint you with the fact that they are existent and known to
those familiar with this subject.

Voluntary Transmission of Mental Vibrations.

Under the head of Voluntary Transmission of Mental Vibrations may be
placed the following two general classes of phenomena, viz., (1)
Voluntary Efforts to Exert Mental Influence upon Others; and (2)
Voluntary Efforts to Produce the Phenomena of Telepathy, along

presented for your inspection and consideration.

phenomena formerly classed as "Magic"--and by this we mean both White
Magic, or efforts to produce results beneficial to the person
influenced, and Black Magic, or efforts to produce results beneficial to
the person exerting the influence, and often to the positive detriment
of the person influenced.

WHITE MAGIC. Under the category of White Magic may be placed all those
efforts of mental healing, and similar phases of metaphysical
therapeutics; and the accompanying efforts directed toward the general
happiness and welfare of the person "treated." The word "treatment" has
sprung into use in this connection, in America and Europe, by reason of
its employment by the numerous metaphysical cults and schools
flourishing there. We hear on all hands of persons being "treated" for
Health, Happiness, and Prosperity in this way. While in some cases, the
"magic" is worked on higher planes than those of thought-vibrations, it
is nevertheless true that in most instances the entire pr
