As a divinatory line, six at the sixth place of Abundance reads within the hexagram's overall concern with progress and development; when a king has reached this point there is no need for anxiety, let him be like the sun at noon. 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 house made great and the establishment screened, peering through the door and finding it still and no one there, for three years nothing is seen, evil, 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, Zhen 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 Abundance turns Zhen into Li while the other trigram, Li, stays as it is, which yields Abundance's changing partner, The Clinging (King Wen 30), the hexagram this line is recorded as transforming into.
