Huatou is a skillful method for breaking through the prison of mental habits into the spacious mind of enlightenment. The huatou is a confounding question much like a Zen koan. Typical ones are “What is wu [nothingness]?” or “What was my original face before birth-and-death?” But a huatou is unlike a koan in that the aim is not to come up with an answer. The practice is simple: ask yourself your huatou relentlessly, in meditation as well as in every other activity. Don’t give up on it; don’t try to think your way to an answer. Resolve to live with the sensation of doubt that arises, and it will pervade your entire existence with a sense of profound wonder, ultimately leading to the shattering of the sense of an independent self.
