"...one of the brain's functions could be to be sensitive to more and more subtle levels of being; the brain could then function more as an antenna to pick up such levels rather that as something that would be only the 'initiator' of action. As long as the brain is following only its own internal goals, then it will be occupied; and that's necessary in certain contexts. But if we consider that it's also necessary to reach or contact the unlimited, then there must be silence - a lack of occupation."
