Baoguang (葆光)
Baoguang 葆光, the 'concealed light' — the Zhuangzi's term for a storehouse that pours in without filling and ladles out without emptying: the tradition's own light-word, which names not brightness but the hidden depth that nothing exhausts.
The term
葆光 (bǎoguāng) — 葆, to shelter and keep hidden; 光, light. The term closes a passage in ch. 2 that builds toward it through five negations — 大道不称 (the great Way is not named), 大辩不言 (the great argument does not speak), 大仁不仁, 大廉不嗛, 大勇不忮 — each displayed form failing its own virtue. Then the passage asks: 孰知不言之辩、不道之道？ — who knows the argument without words, the Way without a way? And answers in two images, one noun and one verb: 天府, the heavenly storehouse — 注焉而不满，酌焉而不竭，而不知其所由来 — pour into it and it does not fill, ladle out of it and it does not empty, and no one knows where it comes from; and 葆光, the concealed light — the storehouse’s radiance, known precisely by not being shown.
Why the term matters
- A depth-image, not a brightness-image. The tradition’s own light-word is built from pouring and ladling — capacity, not brilliance. The site’s light problem page holds the practical distinction this term makes from inside the tradition: practitioners report seeing light (imagery in the visual field, registered and bounded there), while the book’s 葆光 is a claim about the unseen source — 而不知其所由来. The two are not enemies, but they are not the same word, and the site keeps the tradition’s word for the hidden one.
- The dark mirror’s family. The scholarly reading (registered in verification) links 葆光 to the Daodejing’s 玄览 — the dark mirror — and 玄德, hidden virtue: the sage does not display an extraordinary brightness. This is the site’s seeing family in its self-effacing register — 虚室生白 (the empty room’s whiteness), 朝彻 (dawn-clearness), and 葆光 (the sheltered light) are three ways of saying one thing: the light that comes of emptying is not for exhibition.
- The inexhaustible as the standard. 注焉而不满，酌焉而不竭 is the book’s own definition of a depth worth having: something can be poured into endlessly and drawn from endlessly, with no known origin. The site’s water pages — the near-Way of ch. 8, the deep pool of the still mind — are this image’s liquid kin, and the settling practice aims at nothing else: a depth that gives without showing and receives without filling.
- Against the flaunted state. The term’s immediate context is the five negations — and the chapter’s longer argument against 荣华 (the flourishing display of argument). The site’s EXP-021 and EXP-022 pages hold the same line in the practice record: the tradition’s own people warn against performing attainment. 葆光 is the vocabulary: attainment is a storehouse, not a display — and the display is how it leaks.
- The drift, small but real. 葆光 survives in modern Chinese as a learned word for hidden talent or restrained brilliance — the concealment survives, but the source (the inexhaustible storehouse, 不知其所由来) has thinned into mere modesty. The site registers the drift per its idiom discipline: the shell of the word survives; the cosmology is carried only in the chapter.
Sources
- Zhuangzi ch. 2 (Qiwu Lun, inner chapter), the passage: 孰知不言之辩、不道之道？若有能知，此之谓天府。注焉而不满，酌焉而不竭，而不知其所由来，此之谓葆光 — verified against the Wikisource full text, the Dudianji interactive text, and a Zhihu full-text column, which agree verbatim
- A scholarly study of the term and its family (homeinmists, reprinted from the Zhuzi xuekan): the Zhuangzi advocates baoguang rather than a displayed brilliance — the sage is the dark mirror (玄览) of the Daodejing, whose virtue is called hidden virtue (玄德)
