This work investigates the complex intersection of mystical experience and linguistic expression in the life and writings of the twelfth-century Persian Sufi, Ruzbihan Baqli. Carl W. Ernst, a scholar of Islamic studies, utilizes a rigorous historical and philological framework to analyze how Baqli navigated the tensions between personal visionary experience and the established norms of Islamic orthodoxy. By examining primary source manuscripts and historical context, the author argues that Baqli’s rhetoric was a deliberate tool for asserting the legitimacy of his sainthood within the broader tradition of Persian Sufism.

Scholars of Islamic mysticism frequently cite this text as a foundational study for understanding the nuances of Persian Sufi literature. Experts highlight the author's ability to balance dense theological analysis with accessible historical narrative, making it a standard reference for students of religious studies.
