At least since the TV series 'Charmed', we know witches use a 'Book of Shadows'. This book usually contains a lot of spells, charts and recipes and is considered a witch's diary.

But it is important to keep in mind that witches, sorcerer and shamans refer to the spiritual forces of nature, which modern people nowadays do not want to know anything about. Therefore, if someone wants to become a witch, sorcerer or shaman, they must first rediscover the spiritual power of their own nature and lose their fear of the 'wilderness'. This book helps with that.
