Mystical literature can take various forms, such as poetry, prose, dialogue, narrative, biography, autobiography, commentary, treatise, or scripture.
It can also use various genres, such as allegory, metaphor, symbol, paradox, analogy, or apophatic language.
Mystical literature can be both descriptive and prescriptive, both informative and transformative, both objective and subjective.
