The carnal soul is a follower of Pharaoh: beware, do not satisfy it, lest it remember its ancient infidelity.
نفس فرعونیست هان سیرش مکن ** تا نیارد یاد از آن کفر کهن
Without the glowing heat of the fire (of mortification) the carnal soul will never become goodly: hark, do not beat the iron till it has become like live coals.
بی تف آتش نگردد نفس خوب ** تا نشد آهن چو اخگر هین مکوب
Without hunger the body makes no movement (towards God): ‘tis cold iron thou art beating. Know (this for sure)!
