Hexagram 51 震 changing to hexagram 49 革
Changing lines (counted from the bottom): 3, 5.
What to read
Two changing lines: read both line texts of the original hexagram; the upper one is the main one. (Rule set out by Zhu Xi in the Yixue qimeng.)
Hexagram 51 震, line 5
震往來厲，億无喪，有事。
The fifth line, divided, shows its subject going and coming amidst the startling movements (of the time), and always in peril; but perhaps he will not incur loss, and find business (which he can accomplish).
Hexagram 51 震, line 3
震蘇蘇，震行无眚。
The third line, divided, shows its subject distraught amid the startling movements going on. If those movements excite him to (right) action, there will be no mistake.
The two hexagrams
Hexagram 51 震 — judgment
亨。震來虩虩，笑言啞啞。震驚百里，不喪匕鬯。
A"an gives the intimation of ease Kăn development. When (the time of) movement (which it indicates) comes, (the subject of the hexagram) will be found looking out with apprehension, and yet smiling and talking cheerfully. When the movement (like a crash of thunder) terrifies all within a hundred li, he will be (like the sincere worshipper) who is not (startled into) letting go his ladle and (cup of) sacrificial spirits.
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.
