nses the
auric emanations of other persons, such as the auric vibrations, colors,
etc.; currents of thought-vibrations, etc.; but does not see events or
scenes removed in space or time from the observer.

(2) Clairvoyance in Space, in which the clairvoyant person senses scenes
and events removed in space from the observer; and, often also is able to
sense such things even when they are concealed or obscured by intervening
material objects.

(3) Clairvoyance in Time, in which the clairvoyant person senses scenes
and events which have had their original place in past time; or scenes
and events which will have their original place in the future.

I shall describe each of these three classes, with their many variations,
as we reach them in their proper places in these lessons. Before doing so
however, I wish to explain to you the several methods by which clairvoyant
vision is usually induced. These methods may be designated as follows:

(1) Psychometry, or the method of getting en rapport with the astral plane
by means of some physical object connected with the person, thing, or
scene about which you desire to be informed.

(2) Crystal Gazing, etc., or the method of getting en rapport with the
astral plane by means of gazing into a crystal, magic mirror, etc.

(3) Clairvoyant Reverie, or the method of getting en rapport with the
astral plane by means of psychic states in which the sights, sounds and
thoughts of the material and physical plane are shut out of consciousness.

I shall now proceed to give the details regarding each one of these three
great classes of methods inducing clairvoyant vision, or en rapport
conditions with the astral plane.

Psychometry. Psychometry is that form of clairvoyant phenomena in which
the clairvoyant gets into en rapport relation with the astral plane by
means of the connecting link of material objects, such as bit of stone,
piece of hair, article of wearing apparel etc., which has had previous
associations with the thing, person or scene regarding which clairvoyant
vision is required.

Without going into technical occult explanations, I would say that the
virtue of these articles consists entirely of their associative value.
That is to say, they carry in them certain vibrations of past experience
which serve as a connecting link, or associated filament, with the thing
which is sought to be brought into the field of clairvoyant vision.

To reach clairvoyantly a thing, scene, or pe
