Judgment of hexagram 28 大過
棟橈，利有攸往，亨。
Tâ Kwo suggests to us a beam that is weak. There will be advantage in moving (under its conditions) in any direction whatever; there will be success.
Judgment of hexagram 18 蠱
元亨。利涉大川。先甲三日，後甲三日。
Kû indicates great progress and success (to him who deals properly with the condition represented by it). There will be advantage in (efforts like that of) crossing the great stream. (He should weigh well, however, the events of) three days before the turning point, and those (to be done) three days after it.

The changing lines of hexagram 28
| Line | Chinese | Legge |
|---|---|---|
| 4 | 棟隆，吉。有它吝。 | The fourth line, undivided, shows a beam curving upwards. There will be good fortune. If (the subject of it) looks for other (help but that of line one), there will be cause for regret. |
| 5 | 枯楊生華，老婦得其士夫，无咎无譽。 | The fifth line, undivided, shows a decayed willow producing flowers, or an old wife in possession of her young husband. There will be occasion neither for blame nor for praise. |
| 6 | 過涉滅頂，凶，无咎。 | The topmost line, divided, shows its subject with extraordinary (boldness) wading through a stream, till the water hides the crown of his head. There will be evil, but no ground for blame. |
