Bibliomancy
Bibliomancy seeks symbolic guidance in a book passage selected through some form of chance.
How to approach it
Selecting a symbol and interpreting it are separate steps. Knowing the catalogue, positions and rules before a consultation helps clarify what the result actually offers.
An important distinction
The passage also has a literary context; isolating a sentence can change what its author means.
An example to explore
If a passage mentions departure, read the surrounding paragraph and consider what kind of change it evokes for you.
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.
