Just as it is the dreamer himself who unknowingly makes the figures and creates the things which appear to him, so the waking man experiences only his own thoughts of the world. When those thoughts are not there, he is not there. And his world is not there: he and his experiences are contents of the mind. It is not, as commonly fancied, that he has a mind but that he--the ego-thought--is in the mind and never apart from it. The world comes before the waking dreamer just as it comes before the sleeping dreamer, only it comes more coherently and consistently and logically. The mystery of the universe is in the end the mystery of mind. The reasonable question to which scientists should address themselves, and will in the end have to, is "What is Mind?" To call it brain, flesh, is a misleading answer.
