Thirty years ago, before I began to study, I said, 'Mountains are mountains, waters are waters.' After I got insight into the truth of Zen through the instructions of a good master, I said, 'Mountains are not mountains, waters are not waters.' But now, having attained the abode of final rest, I say, 'Mountains are really mountains, waters are really waters.'
Are the three understandings the same or different?
