son. It would be hopeless to plunge
vaguely into space to find a total stranger among all the millions
around us without any kind of clue; but, on the other hand, a very
slight clue would usually be sufficient.

If the clairvoyant knows anything of the man whom he seeks, he will
have no difficulty in finding him, for every man has what may be
called a kind of musical chord of his own--a chord which is the
expression of him as a whole, produced perhaps by a sort of average of
the rates of vibration of all his different vehicles on their
respective planes. If the operator knows how to discern that chord and
to strike it, it will by sympathetic vibration attract the attention
of the man instantly wherever he may be, and will evoke an immediate
response from him.

Whether the man were living or recently dead would make no difference
at all, and clairvoyance of the fifth class could at once find him
even among the countless millions in the heaven-world, though in that
case the man himself would be unconscious that he was under
observation. Naturally a seer whose consciousness did not range higher
than the astral plane--who employed therefore one of the earlier
methods of seeing--would not be able to find a person upon the mental
plane at all; yet even he would at least be able to tell that the man
sought for was upon that plane, from the mere fact that the striking
of the chord as far up as the astral level produced no response.

If the man sought be a stranger to the seeker, the latter will need
something connected with him to act as a clue--a photograph, a letter
written by him, an article which has belonged to him, and is
impregnated with his personal magnetism; any of these would do in the
hands of a practised seer.

Again I say, it must not therefore be supposed that pupils who have
been taught how to use this art are at liberty to set up a kind of
intelligence office through which communication can be had with
missing or dead relatives. A message given from this side to such an
one might or might not be handed on, according to circumstances, but
even if it were, no reply might be brought, lest the transaction
should partake of the nature of a phenomenon--something which could be
proved on the physical plane to have been an act of magic.

Another question often raised is as to whether, in the action of
psychic vision, there is any limitation as to distance. The reply
would seem to be that there should be no limit
