3. _By the projection of a thought-form._--The ability to use this
method of clairvoyance implies a development somewhat more advanced
than the last, since it necessitates a certain amount of control upon
the mental plane. All students of Theosophy are aware that thought
takes form, at any rate upon its own plane, and in the vast majority
of cases upon the astral plane also; but it may not be quite so
generally known that if a man thinks strongly of himself as present
at any given place, the form assumed by that particular thought will
be a likeness of the thinker himself, which will appear at the place
in question.

Essentially this form must be composed of the matter of the mental
plane, but in very many cases it would draw round itself matter of the
astral plane also, and so would approach much nearer to visibility.
There are, in fact, many instances in which it has been seen by the
person thought of--most probably by means of the unconscious mesmeric
influence emanating from the original thinker. None of the
consciousness of the thinker would, however, be included within this
thought-form. When once sent out from him, it would normally be a
quite separate entity--not indeed absolutely unconnected with its
maker, but practically so as far as the possibility of receiving any
impression through it is concerned.

This third type of clairvoyance consists, then, in the power to retain
so much connection with and so much hold over a newly-erected
thought-form as will render it possible to receive impressions by
means of it. Such impressions as were made upon the form would in this
case be transmitted to the thinker--not along an astral telegraph
line, as before, but by sympathetic vibration. In a perfect case of
this kind of clairvoyance it is almost as though the seer projected a
part of his consciousness into the thought-form, and used it as a kind
of outpost, from which observation was possible. He sees almost as
well as he would if he himself stood in the place of his thought-form.

The figures at which he is looking will appear to him as of life-size
and close at hand, instead of tiny and at a distance, as in the
previous case; and he will find it possible to shift his point of view
if he wishes to do so. Clairaudience is perhaps less frequently
associated with this type of clairvoyance than with the last, but its
place is to some extent taken by a kind o
