Source passage

Source text · mention only

In its simplest form (and one which any person can try with astonishing results upon an artless, unsuspicious sitter), a slate, on which, before the sitter's visit, a message has been written, is lying face downward on the table when the séance begins. There are other slates on an adjoining table within easy reach of the Medium. In order that the Medium may be brought into Spiritual relationship with the sitters, contact with the Medium is necessary, and the sitters are therefore requested to place their hands, palms downward, in the middle of the table; on these hands the Medium places his own and the séance begins. Before long, the presence of Spiritual power becomes manifest by raps on the table, or by vibratory movements of the table, more or less violent, and by spasmodic jerkings or twitching of the Medium's arms or body. When sufficient Spiritual power has been generated, the Medium takes up the slate, and, still controlling with his left hand the hands of his sitters, places on it a minute fragment of slate pencil.
