It is easy to suppress: it is easy to express. We do both. We express if the situation allows, and if it is convenient and not dangerous for you. If you can harm the other, and the other cannot harm you, you will express the anger. If it is dangerous, if the other can harm you more, if your boss or whoever you are angry at is more strong, you will suppress it. Expression and suppression are easy, witnessing is difficult. Witnessing is neither; it is not suppressing, it is not expressing. It is not expressing because you are not expressing it to the object of anger. It is not being suppressed either. You are allowing it to be expressed-expressed in a vacuum. You are meditating on it. Stand before a mirror and express your anger and be a witness to it. You are alone, so you can meditate on it. Do whatsoever you want to do, but in a vacuum. If you want to beat someone, beat the empty sky. If you want to be angry, be angry: if you want to scream, scream. But do it alone, and remember your self as a point which is seeing all this-this drama. Then it becomes a psychodrama, and you can laugh at it and it will be a deep catharsis for you. Afterwards you will feel relieved of it and not only relieved of it, you will have gained something through it. You will have matured; a growth will have come to you. And now you will know that even while you were in anger, there was a centre within you which was undisturbed. Now try to uncover this centre more and more, and it is easy to uncover it in desire.
