5.19

舊說及王弼解。妙謂始。徼謂終也。夫觀始要終覩妙知著。達人之鑒也。既以欲澄神昭其妙始。則自斯以已宜悉鎮之。何以復須有欲得其終乎。宜有欲俱出妙門。同謂之玄。若然以往復何獨貴於無欲乎。

The old explanations and Wang Bi’s commentary say that 'subtlety' refers to the beginning, and 'boundary' refers to the end. Now, observing the beginning to anticipate the end, and seeing the subtle to know the manifest, is the discernment of the attained person. If one has already clarified the spirit through desirelessness to illumine its subtle beginning, then from this point on one ought to keep it all settled; why would one again need to have desire to obtain its end? If having desire also emerges from the gate of subtleties and together they are called the mysterious, if that is the case, why should one exclusively value being without desire?
