Usually, we see only the fingers - not the spaces in between. It is simply because we never allow ourselves to be so. We enjoy battling with ourselves and our emotions so much that the battle becomes second nature to us. And we complain that we have no peace of mind. Probably that is the reason why we often do not find it.
Mind is by itself peaceful.
But we do need to do something to our minds in order to be angry or sad. Imagine yourself enjoying a moment of quiet. Suddenly something disturbs your enjoyment. You start up at once, annoyed or angry at the disturbance. Because you dislike the interruption.
