Purchased for $5 at a local used bookstore. This is a fascinating read though, contrary to popular opinion, it is not about worshipping Satan. Instead, LaVey espouses an atheistic philosophy, certainly influenced by Nietzsche, that opposes ethical doctrine laid out by Christianity and the Bible. Satanists are encouraged to indulge rather than abstain, question rather than accept, and enjoy rather than avoid the seven deadly sins. Elements of this doctrine often seem nihilistic and self-centered which turns me off. There are, however, some interesting views discussed in the book, particularly through a philosophical lens. The second half of the book is more esoteric and honestly, silly, as it covers magic, ceremony, and invocations. It is fun to read banned/controversial books and this is no exception. You won’t burn in Hell for reading this book in an attempt to better understand the highly misunderstood Church of Satan.
