Only the concentrated mind can extend its limitations. This is distinct from the way we think they are or might be, or as we'd like them to be, hopefully comfortable and pleasant. But rather birth, decay, disease and death, not getting what one wants, or getting what one doesn't want, a constant perception of what we dislike, because it fails to support our ego-belief. In knowing and seeing things as they really are, we will lose that distaste. No person, no possession, no thought, no feeling.
Nothing can be clung to and found to be steady and supportive.
This is right view, beyond our ordinary every-day perception. It results from right concentration and comes from dealing with dukkha in a positive, welcoming way. When we try to escape from dukkha by either forgetting about it, running away from it, blaming someone else, becoming depressed by it or feeling sorry for ourselves, we are creating more dukkha . All these methods are based on self-delusion. Sometimes our understanding may feel like one of those mystery pictures that children play with.
