The second line of Gathering Together (King Wen 45) is drawn as yin, the numeral six in the old divination manuals. James Legge's translation renders the line as being led forward by an unseen tie, good fortune and no error, if he holds to the sincerity proper to a border sacrifice. The image sits inside a hexagram whose judgment as a whole concerns union and being collected, docile obedience leading on to satisfaction; the king approaches his temple, and firm correctness brings advantage, 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 Kun, earth in Legge's readings of the eight trigrams, while the upper trigram of the hexagram is Dui, lake in the same traditional set of images. The Great Symbolism of the hexagram reads a marsh raised above the earth; the superior man keeps his weapons of war in good repair against contingencies not yet foreseen, and the second line takes its place inside that combined picture of Kun below and Dui above.
Read on its own the line neither opens nor closes the hexagram's argument. It marks the point where Kun is either forming (in the lower trigram) or completing itself (in the upper), and later interpreters treat its image, Being Led Forward by an Unseen Tie, as the concrete case through which the hexagram's abstract judgment becomes visible in a single situation rather than a general principle.
