Hydromancy
Hydromancy covers practices that interpret water, its reflections, movements or shapes as signs.
How to approach it
A reading begins by recognising a sign and relating it to a question. Describe the observation first, then explore its associations: the image opens a reflection rather than imposing a conclusion.
An important distinction
It does not test water quality and has no single historical table of meanings.
An example to explore
Ripples in an image can suggest a spreading change; frame that association as a metaphor.
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.
