Greetings Jerry and Yuri,
That could work, but I still see the “one thread” line as a comment on what precedes, not what follows. Gu Liuxin sees it that way as well, in his commentary on the lun. Here’s my seat-of-the pants translation of his commentary: “Although the movements are ever changing (qianbian wanhua), yet the principle (daoli) of alternation of adhering and giving way (nian zou xiangsheng), and of responding to and following swiftness and slowness, remains consistent (yiguan: one thread).” —Gu Liuxin, _Taijiquan Shu_, China Book Press, Hong Kong, 1985, p. 399.
Gu not only clarifies that li3 is noun—daoli (principle; the hows and whys of something)—but he names its attributes. Remember how this document begins. It begins with a description of the philosophical concept of taiji. Whoever wrote this document was vamping on some familiar themes. Compare, for example, a recorded statement of Zhu Xi, “Master Zhu said: Ji is the end point (jizhi) of the moral order (daoli). The order of all things in Heaven and Earth is Taiji. Taiji is just the single actualized order that runs through them and unifies them.” —trans. Joseph Alder, —online doc. Another word for endpoint is “duan.”
