The Buddhists believed that anger was a kind of tiger within us, one whose claws tear at the body that houses it. To have a chance at stillness—and the clear thinking and big-picture view that defines it—we need to tame that tiger before it kills us. We have to beware of desire, but conquer anger, because anger hurts not just ourselves but many other people as well. Although the Stoics are often criticized for their rigid rules and discipline, that is really what they are after: an inner dignity and propriety that protects them and their loved ones from dangerous passions.
