The fifth place occupies the honored position and serves as the ruler of The Gentle (Wind), whence commands and orders issue. Residing here, it attains the central and correct position, fully embodying the goodness of The Gentle.
Yet The Gentle represents the way of yielding compliance; its benefit lies in persevering correctness. This is not because the fifth lacks strength, but because in The Gentle one must be cautious.
Once correctness is held, good fortune ensues and regrets vanish, leaving nothing that does not bring advantage. Persevering correctness means maintaining the correct center.
When residing in The Gentle and issuing commands, taking the central and correct position always brings good fortune; if one is yielding and compliant without correctness, regret follows—how could there be nothing that does not bring advantage?
When commands issue forth, there are alterations to be made. Having no beginning means that initially things were not yet good; having an end means that altering them brings goodness. If matters were already good, why issue orders? Why alter anything?
'Three days before Geng, three days after Geng: good fortune'—the way of issuing orders and making alterations should be like this. Jia (甲) marks the beginning of affairs; Geng (庚) marks the start of alteration.
Among the ten Heavenly Stems, Wu and Ji form the center; once the center is passed, change occurs, hence it is called Geng. When reforming affairs, one must trace them from beginning to end, just as with the meaning of 'three days before Jia and three days after Jia.'
Acting in this way brings good fortune. The detailed explanation is found in Hexagram Gu (Work on What Has Been Spoiled).
