This book discusses issues of mystical theology, including the divine darkness, the affirmations and negations concerning God, super essential radiance, and the influence of jewels on some of the mystics. The celestial hierarchies section includes discussions concerning the nature of hierarchy, the first order of celestial beings, dominions, virtues and powers, and what the traditional number of angels signifies.
Starts well. The creator spirit cannot be known. God can be loved but not thought of. Once the author warms to the issue of Mystical Hierachies he completely loses the reader. Compound words and sentences exceeding 100 words in length are not conducive to the imparting of knowledge or fostering understanding. His contemporaries must have thought him as mad as his name.
