“If the left hemisphere of the brain goes on dominating you, you will live a successful life—so successful that by the time you are forty you will have ulcers; by the time you are forty-five, you will have had at least one or two heart attacks. By the time you are fifty you will be almost dead—but successfully dead! You may become a great scientist, but you will never become a great being. You may accumulate enough wealth, but you will lose all that is of worth. You may conquer the whole world like an Alexander, but your own inner territory will remain unconquered.”
