Based on a correspondence course circulated among American students of Druidry in the early 20th century, and reconstructed from the surviving fragments by widely respected Druid and occultist John Michael Greer, the Dolmen Arch is a comprehensive course of Druid occultism and nature spirituality. This second volume contains extensive instruction in the three grades of the Greater Mysteries -- the Gradd y Gwyddon y Ffordd (Grade of the Loremaster of the Path), Gradd y Gwyddon y Cylch (Grade of the Loremaster of the Circle), and Gradd y Gwyddon Rhydd (Grade of the Free Loremaster), comprising more than 100,000 words of instruction in the inner teachings of traditional Druid Revival occultism. Along with plenty of philosophy, symbolism, and the hidden meanings of Welsh legend, these lessons cover methods of practical magic, spiritual healing, and the skills needed to teach and initiate students into the mysteries of the Dolmen Arch.
