This volume contains a series of 20 essays by Gerald Yorke, who for four years was one of Aleister Crowley's closest followers, and remained a lifelong friend. Although in later life he embraced Buddhism, Yorke was one of the handful of people who laboured to preserve the legacy of "The Beast" after his death in 1947, and through his work as a publisher's advisor he was also instrumental in the publication of many of the most important works of his times on the occult, yoga and Buddhism. Yorke's profound practical as well as theoretical knowledge of these subjects is reflected in these essays, some of which are published here for the first time. The essays are accompanied by a biographical Introduction by Keith Richmond, a Reminiscence by Timothy d'Arch Smith, and a revised version of Yorke's Crowley Bibliography by Clive Harper. The book concludes with a lengthy Interview with Gerald Yorke by David Tibet, undertaken shortly before Yorke's death in 1983.
