Those who think only of helping others, even if they dont have a master to teach them, are already in the process of becoming a white mage

"Do not be misled into thinking that in order to become a black mage you must have a devilish master to teach you the art of bewitchment or evil conjuration. It is possible, but you do not necessarily need teaching for this. Anyone can become a black mage, without a master, without anything; all they need to do is to allow themselves to be guided by their lower nature. Indeed, people who give a free rein to their bad instincts, who incessantly break the laws of kindness, justice and love, who try to gain at the expense of others, to oust them or destroy them, can do nothing else but become a black mage. And in the same way, those who think only of helping and enlightening others, even if they do not have a master to teach them, are already in the process of becoming a white mage."
