From 'Preponderance of the Small, success' to 'great good fortune.'
Sub-commentary: 'Preponderance of the Small, success': 'Preponderance of the Small' is the name of the Gua. Under Hexagram Great Preponderance, Wang Bi noted: 'Pronounced with the sound of guo as in passing each other.'
Fearing people would take it in the sense of fault and crime, he glossed the pronunciation. Thus the meaning of 'Preponderance of the Small' is the same as that one.
Exceeding in small matters is called Preponderance of the Small, which is what is meant by 'in conduct exceeding in reverence, in mourning exceeding in grief.'
Master Chu said: 'It refers to when the conduct of petty people has minor faults, and the noble person adopts excessively earnest conduct to rectify them, like Yanzi wearing a fox-fur robe.'
This means that because petty people have faults, the noble person acts with excessive earnestness; it does not mean that the Gua's name is explained directly by 'faults and sins.'
The Judgment says: 'Preponderance of the Small: the small exceeds and achieves success,' meaning that through slight excess success is attained, proving it is not sinful guilt.
Therefore Wang glossed the sound under Great Preponderance, clarifying that although the meaning encompasses surpassing faults, it fundamentally refers to the noble person adopting excessive conduct.
Zhou and others failed to grasp this principle and explained the Gua's name solely through guilt and transgression, going far astray. Exceeding in small matters allows the Dao to prevail; hence it says: 'Preponderance of the Small, success.'
'Advantageous to be steadfast': rectifying the world and inspiring custom, advantage lies in returning to correctness; hence 'advantageous to be steadfast.'
'Small matters are permissible, great matters are not permissible' refers to the time: when there are minor errors, one can only rectify them with small matters, not correct them with grand undertakings; hence 'small matters are permissible, great matters are not.'
'The flying bird leaves its sound: not fitting to ascend, fitting to descend, great good fortune': this uses a metaphor to show that excessively earnest conduct can bring good or bad fortune.
The flying bird leaves its cry, mourning as it seeks a perch: if it flies higher, it finds nowhere to settle; if it descends, it does not lose its peace.
This illustrates that when the noble person is in a time of minor errors and practices excessive earnestness, if he establishes himself compliantly, there is good fortune; if he opposes superiors and offends them, there is misfortune.
Hence it says: 'The flying bird leaves its sound: not fitting to ascend, fitting to descend, great good fortune.' Compliance means keeping to humility and dwelling below; defiance means offending the ruler and encroaching on superiors.
Thus the minister's defiance or compliance is analogized to the bird's ascending or descending.
Note: 'The flying bird' to 'seeking a resting place.'
Sub-commentary: 'The flying bird leaves its sound, mourning as it seeks a resting place': 'yi' means lost. When a bird loses its voice, it must be in distress, having found no place to rest. The Analects says: 'When a bird is about to die, its cry is mournful.'
Thus we know that the left-behind sound is a mournful cry.
