When, as a consequence of some insult you become irritated, do not grieve because it has mentally activated the concealed evil within you. Vanquish these thoughts that have sprung up in the knowledge that as they are destroyed when they arise, the evil underlying them that leads them toward action is also destroyed. If these thoughts are allowed to linger and appear often, then evil usually becomes stronger.
