5. The vampire bible The Vampire Bible provides working assumptions that tap the mythic image of the Vampire. The Vampire Bible summarizes specific perspectives about reality that we have found are useful in producing results in the real world. Vampirism advocates measuring the value of an idea not by its truth, but by its usefulness. We judge an idea's usefulness by testing its results when we treat the idea as if it were true. We are completely practical even when it comes to the mythic and magical side of our religion. The Vampire Bible serves as a basic instruction manual for understanding and using a magical perspective that works. In less than fifty pages of condensed and clear language you will learn the essentials of our way of life.
