As time goes on, you will be surprised to find you are aware of your anger sooner than before. This awareness, when it becomes stronger, will spill over to other emotions. You might find yourself watching your desire. In that watching, the desire will resolve and you will be left only with the awareness. Or you may watch sadness.
Sadness is slower to arise and resolve than some other emotions.
The most difficult emotion to watch is depression. But that too can be done with stronger mindfulness. As you get into the swing of it, you will find your awareness becoming sharper. At the same time, the episodes of anger will get shorter and less frequent. As the intensity of anger lessens, you will find you are grappling less and less with your emotions.
