A medium is one whose organism is sensitive to vibrations from the Spirit World and through whose instrumentality, intelligences in that world are able to convey messages and produce the phenomena of Spiritualism. The phenomena of Spiritualism consists of:
- Gift of tongues
- Laying on of hands
- Automatic and independent writing and painting, photography
- Direct and independent voice
- and any other manifestation which proves the continuity of life.
"The office of mediumship is to bless humanity, to enable the race to overcome conditions of matter sufficiently to make such the servant rather than the master of intelligent beings, to enable it to guide (through intuition) the individual for their own and others good." Mary T. Longley from "Teachings and Illustrations As They Emanate From The Spirit World."
