The true happiness is to know exactly what we are doing, why are we doing it, where we will be (after the things we have done), what we will do next, when to do what and when not to do and how we will do it.
To know these things we have to know ourselves, we have we to know why we are created, and we have to know why we are in this life, in this age, in this year or era, in this family, in this country and all the whys questions.
