The third line of Abundance (King Wen 55) is drawn as yang, the numeral nine in the old divination manuals. James Legge's translation renders the line as a curtain so large it hides even the small stars at midday, breaking the right arm, no great error. The image sits inside a hexagram whose judgment as a whole concerns progress and development; when a king has reached this point there is no need for anxiety, let him be like the sun at noon, 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 Li, fire 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 and lightning together; the superior man decides litigation and apportions punishment with exactness, and the third line takes its place inside that combined picture of Li below and Zhen above.
Read on its own the line neither opens nor closes the hexagram's argument. It marks the point where Li is either forming (in the lower trigram) or completing itself (in the upper), and later interpreters treat its image, A Curtain Hiding Even the Small Stars, as the concrete case through which the hexagram's abstract judgment becomes visible in a single situation rather than a general principle.
