In Section 45 of the Hadiqat al-Haqiqah, Sanai provides specific, systematic medical definitions and pathological explanations for various diseases. For example, he defines stroke (sakta) as an obstruction of the brain's ventricles preventing waste clearance, fever (hummayat) as an external heat entering the heart and spreading throughout the body, and describes the physical mechanics of inhalation and exhalation. This detailed poetic exposition demonstrates the assimilation of Galenic-Islamic medical science into mystical and didactic Persian literature.
