Two new chapters on Western Sufism, and one of relevance to it, have just been published in a new book, Esoteric Transfers and Constructions: Judaism, Christianity, and Islam, ed. Mark Sedgwick and Francesco Piraino (New York: Palgrave, 2021). They are:
- "The Sufi Shaykh and His Patients: Merging Islam, Psychoanalysis, and Western Esotericism" by Francesco Piraino, pp. 195-217.
The Sufi shaykh in question is Gabriele Mandel, in Italy, who combines Islam, psychoanalysis, and Western Esotericism.
- "Sufism and the Enneagram" by Mark Sedgwick, pp. 219-246.
Covers the complicated relationship between the Enneagram from Gurdjieff to the Naqshbandiyya.
- "Heretical Orthodoxy: Eastern and Western Esotericism in Thomas Moore Johnson’s 'Platonism'" by Vadim Putzu, pp. 273-296.
Not strictly speaking about Sufism, but important, as Thomas Moore Johnson was the publisher of some of the important articles about Sufism by C. H. A. Bjerregaard, and was also connected in other ways.
