He who is not angry when there is just cause for anger is immoral. Why? Because anger looks to the good of justice. And if you can live amid injustice without anger, you are immoral as well as unjust.

Let anger be guarded against. If it cannot, however, be averted, let it be kept within bounds. For indignation is a terrible incentive to sin. It disorders the mind to such an extent as to leave no room for reason.

Keep this thought handy when you feel a fit of rage coming on — it isn’t manly to be enraged. Rather, gentleness and civility are more human, and therefore manlier. A real man doesn’t give way to anger and discontent, and such a person has strength, courage, and endurance — unlike the angry and complaining. The nearer a man comes to a calm mind, the closer he is to strength.” — MARCUS AURELIUS, MEDITATIONS, 11.18.5b

Anger, unlike fear or sadness, is a moral emotion. It is “righteous.” It aims not only to end the current trespass but to repair any damage done. It also aims to prevent further trespass by disarming, imprisoning, emasculating, or killing the trespasser.

You should be angry. You must not be bitter. Bitterness is like cancer. It eats upon the host. It doesn’t do anything to the object of its displeasure. So use that anger. You write it. You paint it. You dance it. You march it. You vote it. You do everything about it. You talk it. Never stop talking it.

Though anger seems a pessimistic response to a situation, it is at root a symptom of hope: the hope that the world can be better than it is. The man who shouts every time he loses his house keys is betraying a beautiful but rash faith in a universe in which keys never go astray. The woman who grows furious every time a politician breaks an election promise reveals a precariously utopian belief that elections do not involve deceit.
The news shouldn’t eliminate angry responses; but it should help us to be angry for the right reasons, to the right degree, for the right length of time – and as part of a constructive project.
And whenever this isn’t possible, then the news should help us with mourning the twisted nature of man and reconciling us to the difficulty of being able to imagine perfection while still not managing to secure it – for a range of stupid but nevertheless unbudgeable reasons.

That's because no one is born with anger. And when we die, the soul is freed of it. But now, here, in order to move on, you must understand why you felt what you did, and why you no longer need to feel it.

Anger is also an effective way to hide hurt and vulnerability, assert status or dominance, push away fear, and compensate for feeling small or weak. In relationships, arguing or bickering can serve the purpose of keeping others at a comfortable distance. A saying describes anger as a poisoned barb with a honeyed tip.

So anger helps us defend threatened territory — it is just, and it is honest. Not only that — it is healthy. It is widely believed that bottling up anger can kill us, slowly and in three different ways.

anger does not, as Melanthius says, — Displace the mind, and then act dismal things; but it absolutely turns the mind out of doors, and bolts the door against it; and, like those who burn their houses and themselves within them, it makes all things within full of confusion, smoke, and noise, so that the soul can neither see nor hear any thing that might relieve it. Wherefore sooner will an empty ship in a storm at sea admit of a pilot from without, than a man tossed with anger and rage listen to the advice of another, unless he have his own reason first prepared to entertain it.

The problem is that the desire to change is fundamentally a form of aggression toward yourself. The other problem is that our hangups, unfortunately or fortunately, contain our wealth. Our neurosis and our wisdom are made out of the same material. If you throw out your neurosis, you also throw out your wisdom. Someone who is very angry also has a lot of energy; that energy is what’s so juicy about him or her. That’s the reason people love that person. The idea isn’t to try to get rid of your anger, but to make friends with it, to see it clearly with precision and honesty, and also to see it with gentleness. That means not judging yourself as a bad person, but also not bolstering yourself up by saying, “It’s good that I’m this way, it’s right that I’m this way. Other people are terrible, and I’m right to be so angry at them all the time.” The gentleness involves not repressing the anger but also not acting it out. It is something much softer and more openhearted than any of that. It involves learning how, once you have fully acknowledged the feeling of anger and the knowledge of who you are and what you do, to let it go. You can let go of the usual pitiful little story line that accompanies anger and begin to see clearly how you keep the whole thing going. So whether it’s anger or craving or jealousy or fear or depression — whatever it might be — the notion is not to try to get rid of it, but to make friends with it. That means getting to know it completely, with some kind of softness, and learning how, once you’ve experienced it fully, to let go.

"Just by breathing deeply on your anger, you will calm it. You are being mindful of your anger, not suppressing it...touching it with the energy of mindfulness. You are not denying it at all. When I speak about this to psychotherapists, I have some difficulty. When I say that anger makes us suffer, they take it to mean that anger is something negative to be removed. But I always say that anger is an organic thing, like love. Anger can become love. Our compost can become a rose. If we know how to take care of our compost...Anger is the same. It can be negative when we do not know how to handle it, but if we know how to handle our anger, it can be very positive. We do not need to throw anything away," (50).

You may be angry. These are difficult times and you may have a good reason for feeling that way. But imagine a world where instead of holding on to our anger, we use it to channel a more communal sense of love to make up for the lack thereof. What a world it would be.

It is not that I do not get angry. I don't give vent to my anger. I cultivate the quality of patience as angerlessness, and generally speaking, I succeed. But I only control my anger when it comes. How I find it possible to control it would be a useless question, for it is a habit that everyone must cultivate and must succeed in forming by constant practice.
