When the first sign appears, you need to be alert enough to "catch" it before it takes you over. For example, the first sign may be a sudden, strong irritation or a flash of anger, or it may be a purely physical symptom. Whatever it is, catch it before it can take over your thinking or behavior. This simply means putting the spotlight of your attention on it. If it is an emotion, feel the strong energy charge behind it. Know that it is the pain-body. At the same time, be the knowing; that is to say, be aware of your conscious presence and feel its power. Any emotion that you take your presence into will quickly subside and become transmuted.
— Eckhart Tolle
