What you are you must find out. I can only tell you what you are not.
You are not of the world, you are not even in the world. The world is not, you alone are. You create the world in your imagination like a dream. As you cannot separate the dream from yourself, so you cannot have an outer world independent of yourself. You are independent, not the world.
Don't be afraid of a world you yourself have created. Cease looking for happiness and reality in a dream and you will wake up. You not know all the 'why' and 'how', there is no end to questions. Abandon all desires, keep your mind silent and you shall discover.
