The usual pattern of thought creating emotion is reversed in the case of the pain-body, at least initially. Emotion from the pain-body quickly gains control of your thinking, and once your mind has been taken over by the pain-body, your thinking becomes negative. The voice in your head will be telling sad, anxious, or angry stories about yourself or your life, about other people, about past, future, or imaginary events. The voice will be blaming, accusing, complaining, imagining. And you are totally identified with whatever the voice says, believe all its distorted thoughts. At that point, the addiction to unhappiness has set in.
— Eckhart Tolle
