He was one of his generation's best wizards, psychologists, and spiritual teachers with more than six decades of experience in the field of psychology and esotericism. In the last two decades of his life, he was able to perform literal miracles releasing people of deep traumas after just one 40 minutes session. Even the likes of Tony Robbins praised his techniques!
Sadly, he left this world a year ago as a rather hidden gem in the realm of occult sciences. If you are a seasoned magician, reading his books might not reveal any radically new techniques or secrets, but his energy will definitely help you in your practice and guide you toward self-realization. If you're more into tangible magical results (money, sex, power), consider checking out King Solomon's final words. Though most likely King Solomon was just a Jewish myth, his message toward the end of his life, is essential wisdom for any serious aspiring magician.
