The thought that "life is a dream" is a dream.

Where would all of the thoughts of all of the sages of all of the ages be without a breathable atmosphere and oxygenated brain? We can talk about a disembodied "Absolute" and how life and nature are "unreal" but would such thoughts exist, COULD such thoughts exist without the body, brain and the environment that supports it? If we weren't abstract-thinking animals, these kinds of statements/discussions wouldn't hold any attraction for us. Try to talk to a cow about emptiness or "The Absolute" - it will just continue eating grass.
