Dalāʼil al-khayrāt... etc.. دلائل الخيرات... [إلخ]

Attributed to Albertus Magnus, The Book of Secrets is a medieval compendium of natural philosophy, spiritual insights, and occult knowledge.

It contains a mix of scientific observations, alchemical formulas, herbal remedies, and mystical practices.

Merging empirical curiosity with spiritual inquiry, the work reflects the diverse intellectual landscape of the Middle Ages and the era’s fascination with hidden knowledge.
