Instead you spend your time being aware of things and meditating on them. The scientific point of view has wiped out every other view to a point where they all seem primitive, so that if a person today talks about ghosts or spirits he is considered ignorant or maybe nutty. My own opinion is that the intellect of modern man isn't that superior. Those Indians and medieval men were just as intelligent as we are, but the context in which they thought was completely different. Logic exists in the mind.
Numbers exist only in the mind.
I don't get upset when scientists say that ghosts exist in the mind. If all technology stopped, tomorrow, these people whould know how to make out. It would be rough, but they'd survive. That was true. The ghost he pursued was the ghost that underlies all of technology, all of modern sience, all of Western thought.
