As a divinatory line, six at the sixth place of Revolution reads within the hexagram's overall concern with believed in only once it is accomplished, great progress and success, advantage in being firm and correct, so that any occasion for repentance disappears. The line occupies a place proper to 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 the superior man changes as the leopard changes its spots, while lesser men merely change their faces to show outward obedience; going forward now would be evil, but abiding firm and correct brings good fortune, is the particular fortune assigned to this one stage of the situation, not to the hexagram as a whole.
The sixth line corresponds by classical convention with the third line, and the two correspond here, since one line is yin and the other yang. Read together with the trigram it belongs to, Dui in the upper position of the figure, the line marks the far edge of the hexagram, past the point the ruling fifth line governs, 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 sixth line of Revolution turns Dui into Qian while the other trigram, Li, stays as it is, which yields Revolution's changing partner, Fellowship (King Wen 13), the hexagram this line is recorded as transforming into.
