Will the stuff written in the book work for me?
Yes. Just trust yourself without a doubt and meditate regularly.
Its a good book to take from and mesh with your own stuff. Look all over the place and study different forms of magick. Take in the knowledge and apply it personally. The cool thing about magick is its all about intention, and controling your mind, and directing it to your desires. Use grimores to inspire your own magick. And follow your intuition, its like following the white rabbit.
