he existence of these atomic planes and demonstrating their
arrangement, it is difficult to see of what particular use it is to
him at present. Still, there the thing is, and it is an earnest of
greater things to come--of further powers still awaiting development.

There are many similar cases--similar, I mean, not in the possession
of that particular form of sight (which is unique in my experience),
but in showing the development of some one small part of the full and
clear vision of the astral and etheric planes. In nine cases out of
ten, however, such partial clairvoyance will at the same time lack
precision also--that is to say, there will be a good deal of vague
impression and inference about it, instead of the clear-cut definition
and certainty of the trained man. Examples of this type are constantly
to be found, especially among those who advertise themselves as "test
and business clairvoyants."

Then, again, there are those who are only temporarily clairvoyant
under certain special conditions. Among these there are various
subdivisions, some being able to reproduce the state of clairvoyance
at will by again setting up the same conditions, while with others it
comes sporadically, without any observable reference to their
surroundings, and with yet others the power shows itself only once or
twice in the whole course of their lives.

To the first of these subdivisions belong those who are clairvoyant
only when in the mesmeric trance--who when not so entranced are
incapable of seeing or hearing anything abnormal. These may sometimes
reach great heights of knowledge and be exceedingly precise in their
indications, but when that is so they are usually undergoing a course
of regular training, though for some reason unable as yet to set
themselves free from the leaden weight of earthly life without
assistance.

In the same class we may put those--chiefly Orientals--who gain some
temporary sight only under the influence of certain drugs, or by means
of the performance of certain ceremonies. The ceremonialist sometimes
hypnotizes himself by his repetitions, and in that condition becomes
to some extent clairvoyant; more often he simply reduces himself to a
passive condition in which some other entity can obsess him and speak
through him. Sometimes, again, his ceremonies are not intended to
affect himself at all, but to invoke some astral entity who will give
him the required information; but of course that is a case of
