How To Develop Mediumship
Anyone is entitled to be considered a "medium" if he or she is
psychically sensitive and capable of receiving and responding to spirit
control or influence. Likewise, anyone is entitled to the designation
who is capable of so generating freely a sufficient quantity of "psychic
force," magnetism, prana, or whatever other name we may choose to apply
to the force which is generated in the human organism and is capable of
being employed by the spirits in order to produce mediumistic phenomena
of the class usually referred to as "physical phenomena." As we have
seen, the spirits themselves are not usually able to manufacture or
generate by themselves this psychic required to produce the said
phenomena, but, on the contrary, must depend upon mediumistic
individuals for such force.
