Book excerpt: Originally published in 1975, Experience of the Inner Worlds is a classic magical textbook of the Western Mystery Tradition. Covering a wide range of topics within a Christian-oriented Qabalistic framework, Gareth Knight explains the difference between magic and mysticism, natural and revealed religion, monism and theism. He also covers the practicalities, examining methods of inner plane communication, contact with the Masters, the 'consciousness' approach of Carl Jung, the vision of Dante and the archetypal power of the Hebrew alphabet - all within the context of the Qabalistic Tree of Life. The book also contains powerful visualisation exercises and examples of communication with angelic and elemental contacts. While this book can be used as a course of self-instruction, it is also an important modern reference book of magical theory and practice, and has been used for decades by students of Western Qabalah and magic.
