"Do not turn to Yid'oni"—Leviticus 19:31.
We are forbidden from employing the idolatrous practice of Yid'oni.
The Yid'oni practice consisted of inserting into one's mouth a bone from the yidoa fowl. After then burning incense, saying certain formulas and doing certain rites, the person would enter a trance-like state, and he would begin issuing predictions about the future.
