The two hexagrams
Hexagram 63 既濟 — judgment
亨小。利貞。初吉終亂。
Kî Zî intimates progress and success in small matters. There will be advantage in being firm and correct. There has been good fortune in the beginning; there may be disorder in the end.
Hexagram 49 革 — judgment
已日乃孚，元亨。利貞。悔亡。
(What takes place as indicated by) Ko is believed in only after it has been accomplished. There will be great progress and success. Advantage will come from being firm and correct. (In that case) occasion for repentance will disappear.
