Small Preponderance, Line 3

The third line of Small Preponderance (King Wen 62) is drawn as yang, the numeral nine in the old divination manuals. James Legge's translation renders the line as taking no unusual precaution against danger, so that someone may come to assail and injure him, evil. The image sits inside a hexagram whose judgment as a whole concerns progress and attainment, but advantage in being firm and correct; small affairs may be undertaken but not great ones, as with a bird flying past that leaves its cry behind, for whom it is not fitting to ascend but only to descend, and there great good fortune, and this line supplies one stage of that larger reading rather than a complete statement on its own.

Structurally the line stands at the topmost place of the lower trigram Gen, mountain in Legge's readings of the eight trigrams, while the upper trigram of the hexagram is Zhen, thunder in the same traditional set of images. The Great Symbolism of the hexagram reads thunder above a mountain; the superior man in his conduct exceeds a little in humility, in mourning exceeds a little in sorrow, and in expenditure exceeds a little in economy, and the third line takes its place inside that combined picture of Gen below and Zhen above.

Read on its own the line neither opens nor closes the hexagram's argument. It marks the point where Gen is either forming (in the lower trigram) or completing itself (in the upper), and later interpreters treat its image, Taking No Unusual Precaution Against Danger, as the concrete case through which the hexagram's abstract judgment becomes visible in a single situation rather than a general principle.

As a divinatory line, nine at the third place of Small Preponderance reads within the hexagram's overall concern with progress and attainment, but advantage in being firm and correct; small affairs may be undertaken but not great ones, as with a bird flying past that leaves its cry behind, for whom it is not fitting to ascend but only to descend, and there great good fortune. The line occupies a place proper to its own nature in the classical doctrine that odd places favour a firm, yang line and even places favour a yielding, yin line. Its own text, that taking no unusual precaution against danger, so that someone may come to assail and injure him, evil, is the particular fortune assigned to this one stage of the situation, not to the hexagram as a whole.

The third line corresponds by classical convention with the sixth line, and the two correspond here, since one line is yin and the other yang. Read together with the trigram it belongs to, Gen in the lower position of the figure, the line marks the hinge between the two trigrams, the last word the lower trigram gets before the upper trigram takes over, one stage in the six stage movement the hexagram traces from its first line to its last.

A change at this line, from yang to its opposite, is the mechanism the tradition uses to move from one hexagram to another. Flipping the third line of Small Preponderance turns Gen into Kun while the other trigram, Zhen, stays as it is, which yields Small Preponderance's changing partner, Enthusiasm (King Wen 16), the hexagram this line is recorded as transforming into.
