It is a stage that all of those who are striving and competing are competing for it, and it is a kind of life that if you are missing it you are one of the dead. It is a light that if you are without it, you are in and ocean of darkness. Furthermore, it is a medicine or cure that if you are without it, your heart becomes a place of sicknesses. It is a sweetness or pleasure that if you are without it, life becomes a thing of worries and of pain.
