This article examines four mystical treatises by the Safavid scholar Fayd al-Kāshānī (d. 1090/1679). Of the four, al-Kalimāt al-Maknūna (“the Hidden Words”) serves as the basis for the three other versions, al-La'āli', Qurrat al-‘Uyūn, and al-Kalimāt al-Makhzūna, composed at different times for different audiences. Comparison of their structure and content reveals changes that occurred in Kāshānī's presentation of the thought of Ibn ‘Arabī and Mullā Sadrā. Kāshānī's later emphasis on Shi‘i hadith sources says much about the context in which he wrote and perhaps more about his later assessment of the place of sufi cosmology, Islamic philosophy, and scripture in scholarly and popular circles.
