Séance
A séance is a method whereby people attempt to communicate with spirits. The word séance comes from the French word for 'session', 'meeting', from Old French seoir, 'to sit.'
In English, the word came to be used specifically for a meeting of people to receive spiritualistic messages (a sense first recorded in English in 1845).
Procedure
The traditional technique for conducting a séance is from ancient Greece, with some later additions from Christian influence. Four, six, or more people sit around a wooden table, while Séances with five people are avoided since Christ was crucified with five wounds, and five–symbolized by the pentacle (the five-pointed star) is thought to draw sinister forces.
In more modern times, a clear glass bowl filled with olive oil is placed at the center of the table with a drop of blood. To enhance the chances of attracting a spirit the bowl is surrounded by object placed at the compass points. Two candles are positioned on the north and south sides of the bowl. A bible opened to 1 Samuel, chapter 28 (the text details a communication with a spirit) is positioned on the west side with a single piece of quartz on the pages. On the east side is a lily flower. Outside the circle are bell (this drives away spirits), a steel knife (steel, especially with an edge, repels spirits), and some rock salt (Salt thrown into a fire drives away spirits, including demons). These latter objects are regarded as tools for defense against undesired spirits. Those participating in a séance place their hands flat on the table, with the little fingers of each hand touching the hands of the people on either side. During the séance, the participants focus on the bowl at the center of the table. Michel de Nostredame, the famous seer who was also called Nostradamus, sometimes used a bowl of water and this inspired the use of a crystal ball in the eighteenth century.
During the séance, the participants do not speak except for the medium. The circle of hands is maintained throughout and the participants focus on the central bowl. When the medium is finished the bible is closed and the candles extinguished. The following day a bell is rung throughout the house to remove spirts that remain.
Conditions
Séances are believed to be more effective under certain conditions. These include holding them at night when spirits are thought to be more visible, or within an ambient atmosphere such as moving water or rain. Also in occult lore, the moon is believed to exert a powerful influence upon the dead.
It is thought that strong emotions such as anger or terror attracts spirits. Other attractants include fresh blood (menstrual blood is said to draw demons not spirits), quartz, or the presence of spiritually sensitive people, especially women and children. Iron and steel, on the other hand, is thought to repel spirits.
Contact
Contact with a spirit during a séance is thought to occur in various ways, with sensory perceptions said to be the most common. Of these, smell is said to be most frequent, followed by touch (a cold spot may be perceived), then auditory, and finally visual, the rarest. Indirect contact in the form of a dream, a candle burning blue or an agitated animal is thought to be another possible manifestation of contact.
