Cutting off the nose is called yi, which is injury above; cutting off the feet is called yue, which is injury below. Both above and below are covered by yin, suffering harm; this is the image of cutting off nose and feet.
The fifth is the ruler's position; a ruler's oppression arises when neither superiors nor subordinates offer support. The scarlet sash is the garment of a minister, taking the meaning of walking and coming; hence it is described by the sash.
The ruler's oppression comes from the world not rallying to him; if all under Heaven came, it would not be oppression.
Though the fifth is in oppression, it possesses the virtue of firmness and centrality; below is the firm and central worthy of Nine in the Second Place, joined in Dao and virtue, who will slowly and surely resonate, coming to rescue all under Heaven together from oppression.
Thus it begins in oppression and slowly finds joy. 'Beneficial to offer sacrifices': in matters of sacrifice, one must achieve utmost sincerity and respect before receiving blessings.
When a ruler is in oppression, he should be mindful of the world's distress and seek the world's worthies, exerting utmost sincerity and reverence as in sacrifice; then he can attract the world's worthies and deliver the world from oppression.
Lines Five and Two share the same virtue, yet why is it said that neither superiors nor subordinates support? The answer is: the resonance between yin and yang is a natural resonance, like husband and wife or blood kin whose roles are fixed.
Lines Five and Two are both yang lines, sharing firm and central virtue; they resonate and seek each other out before coming together, like the righteous bond between ruler and minister or friends.
At the onset of oppression, how could superiors and subordinates already support each other? If they supported each other, it would not be oppression; hence they unite slowly and then find joy.
The second line speaks of offering sacrifice (xiangsi) while the fifth speaks of sacrificing (jisi); the general meaning is that one must employ utmost sincerity to receive blessings.
Broadly speaking, ji, si, and xiang are interchangeable; distinctly speaking, ji is for heavenly spirits, si is for earthly deities, and xiang is for human ghosts.
The fifth, as the ruler's position, speaks of ji; the second, being below, speaks of xiang: each according to what is fitting.
