In the past, kong-an (koan) practicing meant checking someone's enlightenment. Now we use kong-ans to make our lives correct. . . . You must use kong-ans to take away your opinions. When you take away your opinions, your mind is clear like space, which means from moment to moment you can reflect any situation and respond correctly and meticulously.
