The two hexagrams
Hexagram 13 同人 — judgment
同人于野，亨。 利涉大川，利君子貞。
Thung Zăn (or 'Union of men') appears here (as we find it) in the (remote districts of the) country, indicating progress and success. It will be advantageous to cross the great stream. It will be advantageous to maintain the firm correctness of the superior man.
Hexagram 18 蠱 — judgment
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.
