“We are pleased to offer you our service of ŋgam dù spider divination. You are invited to ask a question to the spider, but be aware that it may be modified by us in order to help the spider understand your query.
Spiders could once speak but now communicate using only leaf-cards inscribed with specific symbolic meanings. When asked a question, the spider will respond by manipulating the cards to indicate which direction should be taken, and this will be interpreted by us.
Even if we have asked a question that seems clear, the spider may respond in effect by saying we should ask a different question! Nothing is simple in the world and the spider knows that the questions must reflect this in one way or another.”
