As a divinatory line, six at the sixth place of Deliverance reads within the hexagram's overall concern with advantage found in the southwest, and if no further operations are called for, good fortune in returning to the old conditions; where there is somewhere to go, early action brings good fortune. 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 a prince shooting a falcon on top of a high wall and taking it, advantageous in every way, 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 do not correspond here, since both lines share the same character. 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 Deliverance turns Zhen into Li while the other trigram, Kan, stays as it is, which yields Deliverance's changing partner, Before Completion (King Wen 64), the hexagram this line is recorded as transforming into.
