monize the apparently somewhat conflicting opinions
of those authorities above quoted concerning the nature of mediumship
and spirit communication. In the first place, the student will remember
that there exist planes of being higher and other than our own
earth-plane, and that the rate of normal vibration on such planes is
much higher than are those upon our own earth-plane. In the second
place, he will remember that beings dwelling and manifesting on these
higher planes are able to communicate only by means of their higher
vibratory rate of manifestation. And, in the third place, he will
remember that a person dwelling on the earth-plane will not ordinarily
register and interpret these higher vibrations of communication; and
that it is necessary for such a person to have originally, or else have
developed, the capacity to raise his or her own vibrations to the key
necessary to "catch" these higher vibrations. In short, we have here
once more another instance of that "attunement" between sender and
receiver the most common instance of which is the wireless telegraph.

Psychic Attunement.

The entity, or spirit, dwelling on one of the many higher planes of
being who wishes to communicate with persons on earth through a medium,
must first select some person capable of raising his or her own
vibratory rate of consciousness to become "in tune" with that of the
spirit himself. Then he must learn to project his own mental vibrations
with sufficient intensity and force to be "caught" by the sensitive
perceptive organism of the medium. These things are beyond the
understanding and accomplishment of many decarnate spirits, and unless
they are taught by some one on their own plane of existence they are
likely to fail in their attempts to communicate through a medium on the
earth-plane. But at the present time, in view of the great interest
being manifested "over there" in the communication with the earth-plane,
an earnest, persevering spirit will usually have comparatively little
difficulty in finding a proper instructor, and in acquiring the art of
"earth-plane communication," as it is called on the spirit plane.

The Development of Mediumship.

As regards the acquirement of mediumship qualities, information and
scientific instruction is much needed, particularly at the present time.
In this book we shall endeavor to throw much light upon this particular
matter, and to give such instruction and information in a plain,
