The second line of The Joyous (King Wen 58) is drawn as yang, the numeral nine in the old divination manuals. James Legge's translation renders the line as pleasure arising from inward sincerity, good fortune, and any occasion for repentance disappears. The image sits inside a hexagram whose judgment as a whole concerns progress and attainment, but advantage lies 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 Dui, lake 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 two joined marshes, one above the other; the superior man encourages friends in conversation and in the practice they share, and the second line takes its place inside that combined picture of Dui below and Dui above.
Read on its own the line neither opens nor closes the hexagram's argument. It marks the point where Dui is either forming (in the lower trigram) or completing itself (in the upper), and later interpreters treat its image, The Pleasure Arising from Inward Sincerity, as the concrete case through which the hexagram's abstract judgment becomes visible in a single situation rather than a general principle.
