Life should be like a pleasure trip. When we see a beautiful sight, a pretty house, or a flower on the way, we look at it and enjoy it. We enjoy the sights but we do not linger there, we simply move on.
We need to focus on our destination. Let the thoughts arising in your mind pass by, like watching scenery through the window of a car. The thoughts cannot affect you if you don't allow them to capture your attention.

What is to be done in order to obtain peace? We should live our life understanding and discriminating between the eternal and the non-eternal.
