You must control and direct your emotions not abolish them. Besides, abolition would be antimissile task. Emotions are like a river. Their power can be dammed up and released under control and direction, but is cannot be held forever in check. Sooner or later the dam will burst, unleashing catastrophic destruction.你必须控制并导引你的情绪而非摧毁它，况且摧毁情绪是一件不可能的事情。情绪就像河流一样，你可以筑一道堤 防把它挡起来，并在控制和导引之下排放它，但却不能永远抑制它，否则那道堤防迟早会崩溃，并造成大灾难。
Your negative emotions can also be controlled and directed. PMA and self-discipline can remove their harmful effects and make them serve constructive purposes. Sometimes fear and anger will inspire intense action. But you must always submit your negative emotions--and you positive ones--to the examination of your reason before releasing them. Emotion without reason is a dreadful enemy.
你的消极心态同样也可被控制和导引，积极心态和自律 可去除其中有害的部分，而使这些消极心态能为目标贡献力 量。有的时候恐惧和生气会激发出更彻底的行动，但是在你释放消极情绪(以及积极情绪)之前务必要让你的理性为它们做一番检验，缺乏理性的情绪必然是一位可怕的敌人。
What faculty provides the crucial balance between emotions and reason? It is your willpower, or ego, a subject which will be explored in more detail below. Self-discipline will teach you to throw your willpower behind either reason or emotion and amplify the intensity of their expression.
Both your heart and your mind need a master, and they can find the master in your ego. However, your ego will fill their role only if you use self-discipline. In the absence of self-discipline, your mind and heart will fight their battles as they please. In this situation the person within whose mind the fight is carried out often gets badly hurt.
