I've always told people that for each person there is a sentence--a series of words--which has the power to destroy him. When Fat told me about Leon Stone I realized (this came years after the first realization) that another sentence exists, another series of words, which will heal the person. If you're lucky you will get the second; but you can be certain of getting the first: that is the way it works. On their own, without training, individuals know how to deal out the lethal sentence, but training is required to deal out the second.
