It's a difficult and strange subject matter. We sometimes can say we are happy. Being in a state of happiness is not something that is totally produceable from the efforts of the self. It is a balance achieved between oneself and all that is around. That balance can form a connection between different aspects of the mind, between being and doing. In a very real sense, happiness arises as an absence of annoyances and a state of feeling at home without pressure to change or do. How often do you experience happiness.
