 Most commonly mistaken as a Book of Shadows, a grimoire is not as personal as its counterpart and in fact, a grimoire doesn't contain any personal writings inside.The only contents found in a grimoire would be information on spells, rituals, the preparation of magickal tools, and lists of ingredients and their magickal correspondence.In this manner, while all "books on magic" could be thought of as grimoires, not all "magical books" should be thought of as grimoires.
