The Rosicrucian Science of Initiation

This is really long and consists of 11 parts (for a total of @1.8 hours), but the presenter is one of most articulate persons I've had the pleasure of listening to on a subject as esoteric as this one. I wouldn't say this is strictly Rosicrucian (and all orders are a bit different, anyway), but on the general subject of initiation in mystical traditions, it's a thorough review if you can stick with him.
