I've read that visualisation and "unfolding" (not: forcing) your emotions toward your desire / goal is more powerful than any words. I think it is correct, according to my understanding on how magic(k) works. In short, it is not about the mental / verbal part (typically related to the left part of brain), but to the creative / imaginative part (typically applying to the astral level). This is what magic(k) is about. Which doesn't imply that you cannot use affirmations, which also have an effect.
