héngAlso known as “Duration” (Wilhelm/Baynes) and “Hăng” (Legge)
durationconstancyendurance
In plain words
Thunder and wind moving together without end: the lasting. Success and no blame for persevering in the right way; constancy is not standing still but moving reliably.
The attitude it asks for
Keep your direction and your commitments; change your methods, not your principles.
Structure
Upper trigram☳震Zhen (the Arousing)雷 · thunder · Wood
Hăng indicates successful progress and no error (in what it denotes). But the advantage will come from being firm and correct; and movement in any direction whatever will be advantageous.
Hăng denotes long continuance. The strong (trigram) is above, and the weak one below; (they are the symbols of) thunder and wind, which are in mutual communication; (they have the qualities of) docility and motive force; their strong and weak (lines) all respond, each to the other:—these things are all found in Hăng.
(When it is said that) 'Hăng indicates successful progress and no error (in what it denotes); but the advantage will come from being firm and correct,' this indicates that there must be long continuance in its way of operation. The way of heaven and earth is to be long continued in their operation without stopping.
(When it is said that) 'Movement in any direction whatever will be advantageous,' this implies that when (the moving power) is spent, it will begin again.
The sun and moon, realising in themselves (the course of Heaven), can perpetuate their shining. The four seasons, by their changing and transforming, can perpetuate their production (of things). The sages persevere long in their course, and all under the sky are transformed and perfect. When we look at what they continue doing long, the natural tendencies of heaven, earth, and all things can be seen.
The Image
雷風，恆；君子以立不易方。
(The trigram representing) thunder and that for wind form Hăng. The superior man, in accordance with this, stands firm, and does not change his method (of operation).
爻辭 The six lines
When one line moves, the hexagram becomes another:
上六Six at the top
振恆，凶。
The topmost line, divided, shows its subject exciting himself to long continuance. There will be evil.
Its symbolism
振恆在上，大无功也。
'The subject of the topmost line is exciting himself to long continuance:'—far will he be from achieving merit.
The fifth line, divided, shows its subject continuously maintaining the virtue indicated by it. In a wife this will be fortunate; in a husband, evil.
Its symbolism
婦人貞吉，從一而終也。夫子制義，從婦凶也。
'Such firm correctness in a wife will be fortunate:'—it is hers to the end of life to follow with an unchanged mind. The husband must decide what is right, and lay down the rule accordingly:—for him to follow (like) a wife is evil.
The third line, undivided, shows one who does not continuously maintain his virtue. There are those who will impute this to him as a disgrace. However firm he may be, there will be ground for regret.
Its symbolism
不恆其德，无所容也。
'He does not continuously maintain his virtue:'—nowhere will he be borne with.
The first line, divided, shows its subject deeply (desirous) of long continuance. Even with firm correctness there will be evil; there will be no advantage in any way.
Its symbolism
浚恆之凶，始求深也。
'The evil attached to the deep desire for long continuance (in the subject of the first line)' arises from the deep seeking for it at the commencement (of things).
Shown in the classical Chinese with James Legge's English (1882).
