The Psychic Telephone System
The medium should ever strive to guard against this harmful mental
state, and should open himself completely to the spirit influence,
casting aside all fear and doubt, and placing all responsibility upon
the controlling spirit or band of helpers. The medium should remember
that he is merely the "medium" or psychic telephone system, and is not
an active party to the process of spirit communication. He should,
therefore, never either unduly strive to please, nor be fearful or
distrustful concerning the validity of the manifestation being made
through him. Let the spirits attend to their end of the line, and the
sitters to the other end--the medium is on neither end of the line, but
is the line itself.
