目失镜，则无以正须眉；身失道，则无以知迷惑。
释义Explanation
这句话以镜子为喻，阐明了外在规范与内在修养的重要性。眼睛若失去镜子，便无法整理面容；人若偏离大道，就无法明辨是非、解除困惑。韩非强调，个人需要不断反省并遵循客观法则，才能保持清醒的认知和正确的行为方向。
Using the metaphor of a mirror, this saying emphasizes the necessity of both external reference and inner cultivation. Just as one cannot groom without a mirror, a person who loses the Dao cannot judge right from wrong or dispel bewilderment. Han Fei stresses the need for constant self-reflection and adherence to objective principles to maintain clarity and correct conduct.
