" When we extinguish our ideas of more and less, is and is not, we attain the extinction of ideas and notions, which in Buddhism is called nirvana. The ultimate dimension of reality has nothing to do with concepts. It is not just absolute reality that cannot be talked about. Nothing can be conceived or talked about. Take, for instance, a glass of apple juice. You cannot talk about apple juice to someone who has never tasted it. No matter what you say, the other person will not have the true experience of apple juice. The only way is to drink it. It is like a turtle telling a fish about life on dry land. You cannot describe dry land to a fish. He could never understand how one might be able to breathe without water. Things cannot be described by concepts and words. They can only be encountered by direct experience. "
