Your true knowledge comes from your own life experience. Despite the fact that you are always accumulating experience and knowledge,your life is not exclusively restriced to it. Rather it is about fulfillment,success and joy. Your life serves to express your true self.
A single moment of awakening in this world is eternity in the world to come.
The inner peace of the world to come is living in this world with full attention.
The two are one; flip sides of a coin forever tumbling and never caught.
