Learn to master yourself-to understand both your fears and your desires. That's the key to magic. Then, no one shall have any hold over you. Remember... the magic (sic)... is a living thing, joined to whomever it touches and changed by them as well... You must come to know everything-even your darkest corners. Especially those...Everything has its price.
