Hexagram 21 噬嗑 changing to hexagram 41 損
Changing lines (counted from the bottom): 2, 4.
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 21 噬嗑, line 4
噬乾胏，得金矢，利艱貞，吉。
The fourth line, undivided, shows one gnawing the flesh dried on the bone, and getting the pledges of money and arrows. It will be advantageous to him to realise the difficulty of his task and be firm,—in which case there will be good fortune.
Hexagram 21 噬嗑, line 2
噬膚滅鼻，无咎。
The second line, divided, shows one biting through the soft flesh, and (going on to) bite off the nose. There will be no error.
The two hexagrams
Hexagram 21 噬嗑 — judgment
亨。利用獄。
Shih Ho indicates successful progress (in the condition of things which it supposes). It will be advantageous to use legal constraints.
Hexagram 41 損 — judgment
有孚，元吉。无咎，可貞，利有攸往。曷之用？二簋可用享。
In (what is denoted by) Sun, if there be sincerity (in him who employs it), there will be great good fortune:—freedom from error; firmness and correctness that can be maintained; and advantage in every movement that shall be made. In what shall this (sincerity in the exercise of Sun) be employed? (Even) in sacrifice two baskets of grain, (though there be nothing else), may be presented.
