According to the Buddha, the main cause of suffering is this idea we have that there is an “I” or a “me” in all this: that there is an ego. So the ego wants things his way or her way. The best way, I feel, to understand how the ego works is that we have this idea that I am Somebody. So it is really funny that the Somebody wants things his or her own way. The Somebody is such an important person. And when we have this idea, that we are a Somebody, it is very easy to be wounded, to be hurt.
Actually if you analyse the emotions, the emotions are created by this feeling of suffering. Take anger. If Somebody wants others to behave in his way, and then sees that others are not behaving according to his feeling of being Somebody, he gets angry, thinking: they should have behaved according to what this Somebody says.
We are amused. We think it is funny. But when we are Somebody, we do not feel it in that way. We are really hurt, we are really wounded, we are really despondent. Take fear. Fear is related to this. This Somebody might loose something and so Somebody has fear. What about anxiety? This is very important. Somebody might make mistakes. So you are anxious. And if Somebody wants only plusses from others – how can others give minuses to this Somebody? It is impossible. You see, when you analyse it this way, how absurd our behaviour is.
So to see this leads us maybe to develop this sense of absurdity, to see the absurdity of our self-importance. So this is very powerful, when you see the second Noble Truth in this way, how you are creating suffering for yourself; if you can see this clearly, then the way out of suffering also becomes clear to you.
