Geomancy
In divination, geomancy interprets dot figures constructed through rules; its Arabic tradition is known as the «science of sand».
How to approach it
The order of signs forms part of their meaning. Start with the structure and the names of its components, then compare interpretations without mixing different systems.
An important distinction
The sixteen figures of four levels should be distinguished from feng shui and from general observation of earth or stones.
An example to explore
Draw four rows containing one or two dots each: the arrangement identifies a figure, not a quantity of good fortune.
Taking the idea further
To explore further, compare the related concepts and note differences in material, procedure and interpretation. If you open a related tool, read its own rules; sharing a symbol does not mean carrying out the same practice.
