Six in the Fourth Place is yielding yin and has no aid below; it cannot deliver the world from peril. Because it occupies a high position, it speaks of the minister's way of dwelling in peril.
When a great minister faces danger and difficulty, only by winning the ruler's trust through utmost sincerity, making their bond solid and indivisible, and illuminating the ruler's heart, can he secure freedom from blame.
To win the superior's firm trust, one must rely entirely on plain simplicity. Among many rituals and esteemed ornaments, none surpasses the banquet rite; hence it is used as a metaphor, meaning one should not esteem superficial ornamentation, but rely solely on plain simplicity.
Using a single flagon of wine and two baskets of grain, served in earthenware jars—this is the height of simplicity. Being so plainly sincere, one must also 'bring in pledge through the window.' 'Bringing in pledge' refers to the way of entering into a bond with the ruler.
'Window' conveys the meaning of an opening for light. A room is dark, so a window is opened to let in light; 'from the window' means entering through what is illuminated, analogizing the place where the ruler's heart is already clear.
The Book of Songs says: 'Heaven enlightens the people, like flute and ocarina.' Master Mao glosses 'window' as guidance, which also means opening up.
When a minister binds his ruler's heart with loyalty, trust, and good principles, he must enter through what the ruler already understands before he can gain admittance.
The human heart has what is obscured and what is open; what is obscured is the dark place, and what is open is the bright place. One should approach what is bright and address it; seeking trust is then easy. Hence it says 'bring in pledge through the window.'
If one can do this, then despite difficult and perilous times, one will ultimately attain freedom from blame.
For instance, when a ruler's heart is obscured by dissipation, it is obscured precisely because of it; though one forcefully condemns the wrong of dissipation, if he remains unawakened, what can be done? One must extend from matters that are not obscured to awaken his heart.
Throughout history, those who could remonstrate with their rulers never failed to rely on what the rulers already understood.
Therefore, those who were bluntly outspoken often met with opposition, while those who were gentle, profound, and clear-sighted often saw their advice adopted. Take Emperor Gaozu of Han, who loved Consort Qi and wished to change the crown prince; this was his blind spot.
Many ministers disputed it; the principle of principal versus secondary wife and the order of age were not unclear, yet how could they overcome his blindness? The Four Whiteheads were men whose worth Gaozu had long known and respected; this was his unclouded, illuminated heart.
Therefore, relying on what he already understood to approach the matter, he was awakened as easily as turning over his hand. How did the power of the Four Whiteheads compare to Zhang Liang, the ministers, and all the scholars of the realm?
How did the urgency of their words compare to Zhou Chang and Shusun Tong? Yet he followed the former and not the latter simply because of the difference between attacking a blind spot and approaching what was clear.
Likewise, Queen Dowager of Zhao loved her younger son, the Lord of Chang'an, and refused to send him as a hostage to Qi; this was her blind spot of personal affection. Though the ministers remonstrated forcefully, once she was blinded, how could she listen?
Loving her son and wishing him long-lasting wealth and honor was what was clear in her heart. Therefore, Chulong, the Left Master of the Robes, relied on her clarity to guide her with a long-term plan, and she listened immediately like an echo.
This applies not only to advising rulers, but also to teaching. Instruction must build upon a person's strengths; strengths are what is clear in the mind.
Entering through what is clear in their mind and then extending it to the rest is what Mencius called 'perfecting virtue and developing talent.' The Image says: A flagon of wine and two baskets: rigidity and yielding meet.
The Image merely cites the opening phrase, as is often the case. A flagon of wine and two baskets represent the height of simplicity—the way rigidity and yielding meet and interact. Being able to do this, one can ultimately ensure freedom from blame.
What makes the bond between ruler and minister firm and lasting lies only in sincerity. Rigidity and yielding refer to Four and Five, denoting the intersection between ruler and minister.
