The first of a four-volume set; covering the theoretical aspects of the Holy Qabalah from a Thelemic perspective. This follows the author's work on the Greek Qabalah; fully developing the Thelemic Gnosis. Upcoming volumes will cover the Practical Qabalah, Doctrinal Qabalah and finally, the English Qabalah. When all is said and done, the English language will be demonstrated to have created a complete Qabalah in the way that both the Hebrew and Greek languages once did. And further, as the international language today, its importance will be fully demonstrated, as will the philosophical system called Thelema.
