Two people stand before a large image of a meadow filled with demons, each with his or her share of the demon blooms. Each has a speaker placed in his or her vicinity that stimulates speech.

Whenever two persons exchange whispers, it is as if the demons had been summoned by heaven to the rescue. The whole environment is a meadow filled with the most dreadful things.

Whenever both of us take our places opposite one another in a meadow, we hear the same speaker announce, “There is a being at the other end of the rainbow, a human being.”

If both people produce the same speech, then the demon has been exorcized.
