Self Mastery

Emotions cause you pain and they actually dictate behavior to you. In other words when you are emotional you are no longer in control. For example when you are excited (you might think excitement is good) you can't actually think clearly.

The emotion of excitement takes over and leads you. It's not always the best action that is born from excitement and you don't have any control.The same goes for anger. The emotion clouds your judgment and through this you act. You act without using your consciousness. The result is an outcome that is not always favourable and one that you have no control over.
