The Zen practice of "not-knowing" honors the absolute dimension of our lives - even as we engage in "knowing," as necessary, in the relative dimension. It involves centering ourselves in the here-and-now, and recognizing that all "knowing" is ultimately an abstraction and not reality itself. As long as we don't simply attach to not-knowing instead of knowing, the practice can actually help us be more responsible, responsive, compassionate, and effective.
