As a divinatory line, six at the third place of Dispersion reads within the hexagram's overall concern with progress and success, the king approaching his temple, advantage in crossing the great stream, advantage in being firm and correct. The line occupies a place that does not match its own nature in the classical doctrine that odd places favour a firm, yang line and even places favour a yielding, yin line. Its own text, that dispersing all thought of his own person, no cause for repentance, is the particular fortune assigned to this one stage of the situation, not to the hexagram as a whole.
The third line corresponds by classical convention with the sixth line, and the two correspond here, since one line is yin and the other yang. Read together with the trigram it belongs to, Kan in the lower position of the figure, the line marks the hinge between the two trigrams, the last word the lower trigram gets before the upper trigram takes over, 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 third line of Dispersion turns Kan into Xun while the other trigram, Xun, stays as it is, which yields Dispersion's changing partner, The Gentle (King Wen 57), the hexagram this line is recorded as transforming into.
