We always seek to relieve this unsatisfactoriness by craving for more of this or more of that. This brings us to the second of the Four Noble Truths which tells us that the cause of dukkha is rooted in what are known as the three poisons, greed or attachment, anger or hatred and a deluded mind. We tend to be attached to people and material things and when we are separated from them, we suffer regret. We get angry or have aversions to those things that we do not like. Buddhism teaches that anger harms the one who is angry more than the object to which this anger is directed.
Anger causes heating of the blood and an unpleasant appearance.
The more we get angry with someone and they react to our anger the more this anger increases. Anger is unproductive - it doesn t solve any problems. Everything, material or immaterial, is subject to change or impermanence. Perhaps you are sitting comfortably in your chairs at the moment. If you remained fixed in that chair for a month, you would probably find that you are crippled and unable to move.
