Divination
Ashes
Collect ashes from dead fires or the fire place.
Outside, in a place where the wind usually blows at some time, scatter the ashes to a good depth in a rectagular shape on the ground.
While asking your question regarding the future, use a finger to write the word yes in the ashes to the right and no to the left. Leave them undisturbed overnight.
In the morning, study the ashes. If both words are clearly legible, no answer is possible at this time.
If one has been erased by animal tracks, the wind or by some other force, the remaining word reveals the answer to your question.
If both words are gone, again, no answer has been given.
