"-...My teacher said: "There are three types of alchemist: those who are vague because they don't know what they're doing; those who are vague because they do know what they're doing, but who also know that the language of alchemy is addressed to the heart, and not to the mind."

-And the third type?

-Those, who will never hear about alchemy, but who will succeed through the lives they lead, in discovering the Philosopher's Stone..."
