The ancient cult of
Yidoni, practiced in the land of Canaan, combined witchcraft and idolatry in a séance-like ritual to consult spirits. The practitioner would place a bone of a certain species of bird in his mouth, burn incense, recite incantations, and perform other ceremonial acts until he would enter a trance-like state. A voice would then seem to emanate from the bird-bone in his mouth, answering questions about future events. Conceivably, similar rituals could be practiced in the occult world today.
The practitioner of Yidoni is liable to capital punishment in theocratic courts; those who attend and consult such ceremonies also commit a sin under commandment -37.
