First observe, examine, and then start looking into the roots. Why does a certain thing happen again and again? You become angry again and again: examination will simply show you that anger comes and goes. Investigation will show you the roots of anger, from where it comes -- because it may be, it is almost always so, that anger is only a symptom of something else which is hidden. It may be your ego that feels hurt and you become angry, but the ego keeps itself hiding underground. It is like roots of the trees: you see the foliage but you don't see the roots.
By examination you will see the tree, by investigation you will see the roots. And it is only by seeing the roots that a transformation is possible. Bring the roots to the light and the tree starts dying. If you can find the root of your anger, you will be surprised that the anger starts disappearing. If you can find the root of your sadness you will be again surprised.
