Koan practice means pulling the rug out from under your thinking. When you do this, it becomes starkly clear that thinking has nothing to do with your true nature. Your true nature is before thinking. Kong-ans canâ€™t be approached with your thinking, they must be approached with your confidence. This means asking, â€œDo I believe in myself? Can I trust lifeâ€™s experience this very moment?â€
We may think that confidence is an encyclopedia salesperson ringing a doorbell, confident in what sheâ€™s selling. This isnâ€™t confidence, this is selling yourself something, selling yourself an idea and making it so strong, you canâ€™t be open to the universe. True confidence is completely accepting your not-knowing. Itâ€™s accepting that no one knows and understanding that this is okay. When you do this, your universe becomes bigger. But when you take one idea, formulate something, and become attached to it, your universe shrinks. So let your universe become large. Let your sitting be without boundaries, and a good answer will appear all by itself.
