In the Hadiqat al-Haqiqah, Sanai articulates a paradoxical view of mortality where the 'death of the body' is synonymous with the 'birth of the soul' (mordan-e jesm zadan-e jan-ast). He argues that physical death is not an ultimate end but a transition that even 'death itself' must undergo. Using the metaphor of a mortar (havan), he suggests that while the body is worn down by time and the senses, the soul gains life through the sacrifice of the physical form. This transformation ensures that spiritual existence persists even after the material elements return to their source.
