"What's L.A. without a little occult? Founded in 1934 by Canadian astrologer and all-around mystical man of mystery, Manly P. Hall, Philosophical Research Society is something of a tribute to the man himself. The library is chock full of Hall's esoterica accumulated over the years traveling as a mystic, containing some 50,000 books—a treasure trove of knowledge on obscure and rare religions and philosophies (impressive even if you're not about to hold a seance). When Elvis was going through his divine knowledge era, he sent Priscilla to Philosophical Research Society to do some recon; Charles Bukowski was married by Hall himself on the Society's campus; it's a historically protected building and definitely a major hub of mystical activity. Be ready to stare into the abyss of knowledge." - Maxwell Williams
