The book is the best source of knowledge for those who are interested or fascinated by the MYSTERY OF BRITAIN: the story of King Arthur (true or mythical), Druidry and the mysticism of Merlin. "21 Lessons of Merlin" is dedicated to an amazing period of British history: the "Time of Legends", the foggy Dark Ages. Twenty-one lessons of Merlin contain a huge amount of practical information. Each lesson has one specific magical exercise. These exercises are MAGICAL CEREMONY - "tools of discovery." Here you are dealing with a powerful Archetypal world - an actual place based on historical events that have simply moved to another plane of reality but still exist. And these exercises can help the reader to build "lines of communication" between him and the specific archetypal world with which he wants to establish contact, opening doors to completely new realms of sensations and insights.
