Everything that happens, every event, is just what it is, is entirely patent, revealed, self-evident. But ask it once to fill out that promises, to be not just self-disclosed in the immediate, but all the way from the ground up, and it is struck dumb, it can reveal nothing - whether you are awake or dreaming, who is experiencing this, where it is and how it arises from its background. It is a complete void. Nothing is as it seems, you cannot even ask the question.
