Bringing the needle in — insert. Chapter 27 is the clearest statement in the Suwen of the respiratory timing of insertion, because it gives both techniques and they are opposites: in draining one inserts on an inhalation and withdraws on the exhalation, so that the great qi comes out; in supplementing one inserts at the end of an exhalation and withdraws on an inhalation, so that the qi cannot get out. The reading nà is what makes the phrase a verb; read nèi it would be a location, and the sentence would have no predicate.
Passages where the term does real work, with the original, pinyin and English on the same line.
Every rendering below is a decision about which reader is being addressed. There is no neutral option.
| Wiseman & Feng | insert the needle | They read 内 as nà and render it throughout as insert, which is the only way the timing instructions make sense. |
| Unschuld | push in the needle | Unschuld adds the physical push, which is not in the Chinese but is not wrong for the act; it does however blur the contrast the chapter draws between 内 and 引. |
| This site | inserting the needle | We keep a neutral verb for 内 so that it pairs cleanly with 引鍼 withdrawing; the chapter's whole point is that these two moves are set at opposite phases of the breath, and a vivid verb on one side would spoil the symmetry. |
