The doctrinal expositions that accompany his astonishing account offer extraordinarily prescient insight into many deviations and psychological afflictions of the modern mind, and will be a valuable to psychological practitioners and spiritual counselors as to historians of esoteric history. It also offers a profound corrective to the many brands of New Age 'therapy' that all too unwittingly invoke many of the same elements whose nefarious origins Guenon so clearly described many years ago.
