Geomancy has come through various changes since it originated. It originally dealt with the life of ground or sand. In the ancient time prophets assumed that ground is living. They drew a circle on the ground and they cast sones in it or they drew random marks on the ground from which they later predicted the future.
The most popular way of predicting the future is reading from random lines on the paper which together create a geomantic symbol.
Take a sheet of paper and write your question on it. Then randomly draw four lines of short lines (there must be at least a few short lines on each line). When drawing them, do not count them in any case.
