I shall tell you about a ritual for summoning a ghost, which I
was been told by the freemasons.
You put first a small table against the wall.of your room and cover
it by a white blanket. Then you put a blind mirror, the magic
screen, on that table and lean it against the wall. You put also
two candles in silver holders on both sides of the mirror.
Afterwards you place the symbols of the 4 elements near the corners
of the small table. First a lighted oillamp for the symbol fire,
second a small cup of water for the symbol water, third a
smokecandle for the symbol air and at last a small stone for the
symbol earth. Then you place a crystal rich goblet, symbol for the
Holy Grail, in the center of the small table. A biger banknote you
put then into the goblet.
After you had all that installed you switch off lights in your
room, inflame the two candles, the oillamp, the smokelamp and burn
also the banknote in the crystal goblet, as the sacryfice of your
ritual.
Now you knel down and summon the ghost to appear. You may now see
the summoned ghost in the blind mirror, the magic screen, if you
had made the ritual in the right way.
