What is a Book of Shadows? Well, a Book of Shadows is a personal book a rituals and information on whatever the Witch would like to put in. Some say you should pass your B.O.S down through your family, adding to it each time someone new gets it; others say that each person should have their own; but one that most every one agrees on is that it should be "in your own hand of writ", in your own handwriting. I know, thats alot of writing! But the more energy you put into your B.O.S, the more it is connected to you. This is why most people suggest you make you own tools. The more time, energy, and love you put into something, not only is the final product better but it now contains YOUR essence. This is why even if you pass you book down through the family each person should still add to it.
