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 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.
The changing lines of hexagram 51
| Line | Chinese | Legge |
|---|---|---|
| 1 | 震來虩虩，後笑言啞啞，吉。 | The first line, undivided, shows its subject, when the movement approaches, looking out and around with apprehension, and afterwards smiling and talking cheerfully. There will be good fortune. |
| 2 | 震來厲，億喪貝，躋于九陵，勿逐，七日得。 | The second line, divided, shows its subject, when the movement approaches, in a position of peril. He judges it better to let go the articles (in his possession), and to ascend a very lofty height. There is no occasion for him to pursue after (the things he has let go); in seven days he will find them. |
| 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. |
| 4 | 震遂泥。 | The fourth line, undivided, shows its subject, amid the startling movements, supinely sinking (deeper) in the mud. |
| 6 | 震索索，視矍矍，征凶。震不于其躬，于其鄰，无咎。婚媾有言。 | The topmost line, divided, shows its subject, amidst the startling movements (of the time), in breathless dismay and looking round him with trembling apprehension. If he take action, there will be evil. If, while the startling movements have not reached his own person and his neighbourhood, (he were to take precautions), there would be no error, though his relatives might (still) speak against him. |
