Deliverance in the Order of the Hexagrams: Obstruction means difficulty; things cannot remain in difficulty forever, so it is followed by Deliverance. Things have no principle of unending difficulty; when difficulty reaches its peak, it must disperse.
Deliverance means dispersing; this is why it follows Obstruction. As a Gua, Zhen is above and Kan is below; Zhen is movement, Kan is danger. Moving outside danger means emerging from danger; hence it presents the image of distress and difficulty being dispersed.
Furthermore, Zhen is thunder and Kan is rain; thunder and rain stir when yin and yang interact in harmonious and leisurely dispersal, hence Deliverance. Deliverance is the time when the realm's hardships and perils are dispersed.
The southwest is the direction of Kun; the nature of Kun is vast, level, and easy.
When the world's difficulties have just been resolved and the people have just escaped hardships, one must not govern them again with vexatious severity and urgent pressure; one must relieve them through magnanimity, simplicity, and ease, which is appropriate.
In this way, the hearts of the people will cherish and feel peaceful; hence 'the southwest is advantageous.' Tang eradicated the tyranny of Jie and governed with leniency; King Wu executed the brutality of Zhou and reversed the policies of Shang; both followed ease and leniency.
'If there is nowhere to go, his coming back brings good fortune; if there is somewhere to go, promptness brings good fortune.' 'Nowhere to go' means the world's difficulties have already been dispersed and there is nothing further to undertake.
'Somewhere to go' means there are still matters that should be resolved. When the realm and state fall into misfortune and peril, it is always after principles and laws have decayed into disorder.
Once the sage has resolved the difficulties and all is peaceful and without incident—which is 'nowhere to go'—he should restore the Dao of governance, rectify the guiding principles, clarify the laws, and reinstate the rule of past enlightened kings; this is 'coming back,' meaning returning to correct principles.
It is the good fortune of the entire world. 'Qi' is an initial particle. Since antiquity, sage-kings in rescuing from peril and putting down rebellion had no leisure to act hastily at first; once stability was attained, they established lasting and inheritable governance.
From the Han dynasty downward, once rebellion was removed, rulers undertook no further reform, merely maintaining affairs according to the moment; hence they could not achieve excellent governance, for they did not understand the meaning of 'coming back.'
'If there is somewhere to go, promptness brings good fortune' means that if there are still matters that must be resolved, handling them early brings good fortune.
What ought to be resolved but is not fully eliminated will flourish again if not purged early; emerging problems will gradually grow large if not handled early; hence promptness brings good fortune.
