Development, Line 2

The second line of Development (King Wen 53) is drawn as yin, the numeral six in the old divination manuals. James Legge's translation renders the line as the geese gradually approaching the large rocks, eating and drinking joyfully and at ease, good fortune. The image sits inside a hexagram whose judgment as a whole concerns the marriage of a young lady, and the good fortune attending it, advantage in being firm and correct, and this line supplies one stage of that larger reading rather than a complete statement on its own.

Structurally the line stands at the middle place of the lower trigram Gen, mountain in Legge's readings of the eight trigrams, while the upper trigram of the hexagram is Xun, wind in the same traditional set of images. The Great Symbolism of the hexagram reads a tree above a mountain; the superior man attains to virtue that endures and makes the ways of the people good, and the second line takes its place inside that combined picture of Gen below and Xun 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, The Geese Gradually Approaching the Large Rocks, 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, six at the second place of Development reads within the hexagram's overall concern with the marriage of a young lady, and the good fortune attending it, advantage in being firm and correct. 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. It is also one of the two central lines of the hexagram, the place classical reading treats as the most balanced regardless of the line's own character. Its own text, that the geese gradually approaching the large rocks, eating and drinking joyfully and at ease, good fortune, is the particular fortune assigned to this one stage of the situation, not to the hexagram as a whole.

The second line corresponds by classical convention with the fifth 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 situation settling into its own character, still wholly inside the lower trigram, one stage in the six stage movement the hexagram traces from its first line to its last.

A change at this line, from yin to its opposite, is the mechanism the tradition uses to move from one hexagram to another. Flipping the second line of Development turns Gen into Xun while the other trigram, Xun, stays as it is, which yields Development's changing partner, The Gentle (King Wen 57), the hexagram this line is recorded as transforming into.
