The first line of Pushing Upward (King Wen 46) is drawn as yin, the numeral six in the old divination manuals. James Legge's translation renders the line as pushing upward with the welcome cooperation of those above, great good fortune. The image sits inside a hexagram whose judgment as a whole concerns great progress and success, seeking to meet the great man need cause no anxiety, advance to the south brings 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 lowest place of the lower trigram Xun, wind in Legge's readings of the eight trigrams, while the upper trigram of the hexagram is Kun, earth in the same traditional set of images. The Great Symbolism of the hexagram reads wood in the midst of the earth, growing; the superior man pays careful attention to his virtue and accumulates its small increases until it is high and great, and the first line takes its place inside that combined picture of Xun below and Kun above.
Read on its own the line neither opens nor closes the hexagram's argument. It marks the point where Xun is either forming (in the lower trigram) or completing itself (in the upper), and later interpreters treat its image, Pushing Upward with the Welcome Cooperation, as the concrete case through which the hexagram's abstract judgment becomes visible in a single situation rather than a general principle.
