"Clairvoyance" is used here in
the particular sense indicated by such definition. The student of this
book, therefore, is asked to distinguish Clairvoyance, on the one hand,
from the phenomena of Telepathy or Thought Transference, and, on the
other hand, from the phenomena of communication with entities on other
planes of existence, including the perception of apparitions.

The Phenomena of Clairvoyance.

The phenomena of Clairvoyance may be subdivided (a) according to methods
employed, and also (b) according to general distinctions. The said
classifications follow:

CLASSIFICATION ACCORDING TO METHODS. The classification of Clairvoyant
Phenomena according to methods employed, proceeds as follows: (1)
PSYCHOMETRY, in which the clairvoyant becomes en rapport through the
medium of some physical object connected with the person or scene which
is the object of the en rapport connection; (2) CRYSTAL GAZING, etc., in
which the en rapport connection is established by means of a crystal,
magic mirror, etc., into which the clairvoyant gazes; (3) DIRECT
CLAIRVOYANCE, in which the clairvoyant directly establishes the en
rapport connection by means of raising his or her psychic vibrations so
as to become "in tune" with the finer vibrations of Nature, without the
aid of physical objects.

Classification According to General Distinctions.

The classification of Clairvoyant Phenomena according to general
distinctions, proceeds as follows: (1) PRESENT CLAIRVOYANCE, in which
the objects perceived by the clairvoyant are present in Space and Time,
although invisible to normal sight; (2) SPACE CLAIRVOYANCE, in which the
clairvoyant vision includes objects and scenes removed in space from the
immediate normal perception of the clairvoyant; (3) TIME CLAIRVOYANCE,
in which the clairvoyant perceives objects or scenes removed from him in
past time, or future time.

In order that the student may obtain a comprehensive understanding of
the phenomena of Clairvoyance, we have thought it well to give you a
brief, general outline of the particular phenomena fitting into these
several classes, and to give you, also, a general idea of the principal
methods employed to obtain the phenomenal manifestations in question.
We begin by calling your attention to the three general classes of
method employed to obtain the manifestation of clairvoyant phenomena,
namely: Psychometry, Crystal Gazing, and Clairvoyant Psychic States,
respectively.
