Hey everybody, I recently spotted this book at a local bookstore called The Secret Teachings of All Ages by Manly P. Hall. It's been in print for nearly a century and it's quite the comprehensive tome. It has chapters on many of the figures and mysteries schools mentioned by VM Samael Aun Weor, VM Beezlebub, and Gnosticweb - like Hermes Trismegistus, Atlantis, Rosicrucianism, Egyptian schools, etc. I'm interested in picking this encyclopedia up, but I wonder if much of what's contained in the book is authentic or just information I can do without. Does anyone have any experience with this book or it's author Manly P. Hall? Thank you!
