From 'The Commentary on the Judgment says' to 'without blame.' The Proper Meaning states: 'Return brings smooth progress'—because when yang returns there is smooth progress, it connects smooth progress with return in explaining it.
'The firm returns, moving and proceeding with compliance'—having explained above the meaning of 'Return brings smooth progress,' it further explains below the principle of 'going out and coming in without affliction, friends come without blame,' hence saying 'this is why going out and coming in are without affliction, and friends come without blame.'
The Proper Meaning states: 'Yang Qi first finishes peeling away' means that after yang Qi has finished peeling away, until yang Qi comes returning, seven days elapse in all.
Observing the intent of Wang Bi's commentary, from the exhaustion of yang Qi until its return takes seven days in all; the commentary is clear.
Scholars Chu and Zhuang both said: 'From the fifth month when a single yin arises, to the eleventh month when a single yang arises,' seven months elapse in all; yet it says 'seven days' instead of 'months' because it wishes to show that the growth of yang must be swift, changing 'months' to 'days.'
Now Wang Bi says 'from peeling away to exhaustion' until 'coming to return,' which means seven days pass from exhaustion to return. If one counted from the fifth month, how could one say 'first finishes peeling away'?
Moreover, Approach also marks the growth of yang yet speaks of eight months; why should Return alone alter months to call them seven days?
Looking at the commentary's intent, Wang Bi certainly held this to be otherwise, employing the concept of 'six days and seven-tenths' from the Yi Apocrypha, agreeing with Zheng Xuan's theory, though his wording is abridged and does not elaborate fully.
The Yi Apocrypha: Jilan Tu states: 'The hexagram Qi begins with Inner Truth.' Thus Li, Kan, Zhen, and Dui each preside over one cardinal direction, while the remaining sixty hexagrams each have six lines, each line presiding over one day, totaling 360 days.
The remaining five and one-quarter days—each day being divided into 80 fen, five days make 400 fen, and one-quarter day makes 20 fen, totaling 420 fen.
Distributing this among sixty hexagrams, six sevens are 42, so each hexagram receives seven fen, making six days and seven fen per hexagram. The exhaustion of yang Qi in Splitting Apart occurs at the end of the ninth month; the tenth month belongs to pure The Receptive (Earth).
The Receptive has six days and seven fen. When The Receptive is exhausted, the yang of Return arrives; thus from the exhaustion of Splitting Apart to the return of yang Qi, it is separated by the single hexagram of The Receptive, lasting six days and seven fen.
Expressed in round numbers, Wang Bi says 'seven days in all.' 'Reversing its course' conveys the sense of going out and coming in: fan means entering and turning back; fu means after having turned back, returning upward again.
The Proper Meaning states: 'Reversing its course, in seven days it comes to return; such is the movement of heaven'—uses the movement of heaven to explain 'reversing its course, in seven days it comes to return.'
It means turning back and returning accords with its proper course; returning in only seven days, it cannot stay away long. This is the movement of Heaven.
After Heaven's yang Qi is extinguished, within not more than seven days yang Qi is reborn; this is the natural principle of Heaven, hence called 'the movement of heaven.'
The Proper Meaning states: It uses 'the firm grows' to explain the meaning of 'it is beneficial to have somewhere to go.' 'In Return does one not see the heart of Heaven and Earth?' The Proper Meaning states: 'In Return does one not see the heart of Heaven and Earth?'
praises and illuminates the meaning of Return. Heaven and Earth nourish the myriad things taking stillness as their heart: doing nothing yet things act of themselves, not generating yet things are born of themselves, silent and unmoving—this is the heart of Heaven and Earth.
In this image of Return, 'movement rests within the earth'; thunder is under the earth, resting and unmoving, and its quiet stillness resembles the heart of Heaven and Earth. Observing this image of Return, one 'sees the heart of Heaven and Earth.'
Heaven and Earth have no personal master, so how could they have a mind? Drawing on the human mind, it is ascribed to Heaven and Earth to establish a model.
On the commentary: 'Return means returning to the root' to 'disparate kinds of creatures would never be able to exist together.'
The Proper Meaning states: 'Return means returning to the root'—previously departing from the original place and now returning to it is what is meant by 'returning to the root.' 'Heaven and Earth take the root as their heart'—the root means stillness.
It means Heaven and Earth, silent and unmoving, 'take the root as their heart.' Whenever movement ceases, there is stillness; stillness is not merely the counterpart of movement.
In the movements of Heaven and Earth, stillness is the root and movement is the branch; times of stillness are many, and times of movement are few.
If it stirs momentarily and then ceases, it returns to stillness; thus stillness is not the counterpart of movement, meaning stillness as the root exists naturally of itself, not born as a reaction to movement—hence 'stillness is not merely the counterpart of movement.'
'When speech ceases, there is silence; silence is not merely the counterpart of speech'—speech is the movement of sound; silence is the stillness of the mouth.
When not speaking, one is constantly silent; it is not that silence exists only in contrast to speech, because movement and stillness, speech and silence, are of distinct natures, hence 'not the counterpart.'
'Though Heaven and Earth are vast and richly possess the myriad things, with thunder moving and wind blowing, transforming through ten thousand changes' speaks of the movement of Heaven and Earth.
'Being still and reaching absolute nothingness—this is their root' has two meanings: first, though the myriad things move on the outside, Heaven and Earth remain utterly still within; the outside is the branch and the inside is the root, meaning Heaven and Earth have no deliberate mind.
Second, though thunder moves and wind blows through a thousand changes and ten thousand transformations, once the thunder and wind cease and transformations halt, it likewise returns to quiet and absolute nothingness.
'If they took having form as their heart, disparate kinds of creatures would never be able to exist together'—if one takes nothingness as the heart, then self and other are treated as one, and close and distant are equal, causing no harm to disparate kinds, and both sides find peace.
If one took 'having form' as the heart, the self would remain confined to the self and could not extend universally to creatures, and creatures would remain confined to themselves without relying universally on me; creatures would then be harmed, hence 'they would not be able to exist together.'
