“Magic is a kind of energy. It is given shape by human thoughts and emotions, by imagination. Thoughts define that shape—and words help to define those thoughts. That’s why wizards usually use words to help them with their spells. Words provide a sort of insulation as the energy of magic burns through a spell caster’s mind.”

“I love you." Why it worked right then, why the webbing of my godmother's spell frayed as though the words had been an open flame, I don't know. I haven't found any explanation for it. There aren't any magical words, really. The words just hold the magic. They give it a shape and a form, they make it useful, describe the images within. I'll say this, though: Some words have a power that has nothing to do with supernatural forces. They resound in the heart and mind, they live long after the sounds of them have died away, they echo in the heart and the soul. They have power, and that power is very real. Those three words are good ones.”

“A man's magic demonstrates what sort of person he is, what is held most deeply inside of him. There is no truer gauge of a man's character than the way in which he employs his strength, his power. I was not a murderer. I was not like Victor Sells. I was Harry Blackstone Copperfield Dresden. I was a wizard. Wizards control their power. They don't let it control them. And wizards don't use magic to kill people. They use it to discover, to protect, to mend, to help. Not to destroy.”

“There aren't any magical words, really. Words just hold the magic.”

“Love is another kind of power, which shouldn't surprise you. Magic comes from emotions, among other things. And when two people are together, in that intimacy, when they really, selflessly love each other it changes them both. It lingers on in the energy of their lives, even when they are apart.”

“Magic comes from what is inside you. It is a part of you. You can't weave together a spell that you don't beleive in.”

“The characters within a book were, from a certain point of view, identical on some fundamental level ‒ there weren't any images of them, no physical tangibility whatsoever. They were pictures in the reader's head, constructs of imagination and ideas, given shape by the writer's work and skill and the reader's imagination. Parents, of a sort.”
