As your mindfulness develops, your resentment of change, your dislike of unpleasant experiences, your greed for pleasant experiences and the notion of self hood will be replaced by the deeper insight into impermanence, unsatisfactoriness and selflessness. This knowledge of reality in your experience helps you to foster a more calm, peaceful and mature attitude towards your life. You will see what you thought in the past to be permanent is changing with such an inconceivable rapidity that even your mind cannot keep up with these changes. Somehow you will be able to notice many of the changes. You will see the subtlety of impermanence and the subtlety of selflessness. This insight will show you the way to peace, happiness and give you the wisdom to handle your daily problems in life.
