The Peacock's Egg describes a transformation of the psyche. This is based in the alchemy in which an alchemical dream process is set into motion, acquiring highly resolute manifestation through phases of the opus. An intensive and lengthy occult praxis is entered in which dreams and dreaming practices are developed. Advanced levels of occult experience are attained in which ethereal energy becomes mastered, involving a purification. These attainments adhere to beliefs regarding this type of paranormal experience that include the author's interest in the work of Carlos Castaneda. The intricacies of a crucial alchemical image are described-a Vision of the Peacock's Egg, an accessible metaphysical anatomy. The spatiality of the rose garden, the alchemical death, and attainment of the lapis are then brought into the practice. Contents I. Anatomy of the Peacock's Egg; II. Purification and Renewal; III. The Radiance of Colour; IV. The Amber; V. Phases of the Opus; VI. Dreams; and an appendix on medicine.
