“ The practice of magic also demands the development of what is called the magical will. Will is very much akin to what Victorian schoolmasters called "character": honesty, self-discipline, commitment, and conviction. Those who would practice magic must be scrupulously honest in their personal lives. In one sense, magic works on the principle that "it is so because I say it is so." A bag of herbs acquires the power to heal because I say it does. For my word to take on such force, I must be deeply and completely convinced that it is identified with truth as I know it. If I habitually lie to my lovers, steal from my boss, pilfer from supermarkets, or simply renege on my promises, I cannot have that conviction.Unless I have enough personal power to keep commitments in my daily life, I will be unable to wield magical power. To work magic, I need a basic belief in my ability to do things and cause things to happen. That belief is generated and sustained by my daily actions. If I say I will finish a report by Thursday and I do so, I have strengthened my knowledge that I am a person who can do what I say I will do. If I let the report go until a week from next Monday, I have undermined that belief. If course, life is full of mistakes and miscalculations. But to a person who practices honesty and keeps commitments, "As I will, so mote it be" is not just a pretty phrase; it is a statement of fact. ”
