Abraham Maimonides (1204-1237), who was considered to be the most prominent leader and government representative of all Mamluk Jews, advocating reorganizing Jewish schools to be more like Sufi Hanaqas. Abraham would be the first to attempt borrow ideas and practices from Sufism in his Guide for the Perplexed. His heir Obadyah Maimonides(1228-1265) writes the "Treatise of the Pool" which is a mystical manual written in Arabic and filled with Sufi technical terms. In the book Obadyah lays out how one may obtain union with the unintelligible world showing his full adherence and advocacy of mysticism. He also began to reform practices advocating for celibacy and Halwa, solitary meditation, to better tune yourself to the spiritual plane. These were imitations of long held Sufi practices. In fact, he would often portrayed Jewish patriarchs such as Moses and Issac as hermit who relied on isolated meditation to remain in touch with God. The Maimonides dynasty would essentially spark a new movement amongst Egyptian Jews and thus the Pietist movement was formed.
