Assuredly, in their beginning, all trades (crafts and professions) were (derived) from Divine inspiration, but the intellect added (something) to them.
جمله حرفتها یقین از وحی بود ** اول او لیک عقل آن را فزود
Consider whether this intellect of ours can learn any trade without a master.
هیچ حرفت را ببین کین عقل ما ** تاند او آموختن بیاوستا
Although it (the intellect) was hair-splitting (subtle and ingenious) in contrivance, no trade was subdued (brought under command) without a master.
گرچه اندر مکر مویاشکاف بد ** هیچ پیشه رام بیاستا نشد
If knowledge of a trade were (derived) from this intellect, any trade would be acquired without a master.1300
