Yilin Verse
比目四翼，來安吾國；齎福上堂，與我同床。
Paired eyes, four wings; they come to settle our realm. Bearing blessings up to the hall; they share our bed.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Heaven and fire form Fellowship as mythological creatures of mutual dependence arrive to bless the homeland. Paired-eye fish and shared-wing birds — those legendary beings that can only swim or fly together — come to secure the state. They bring blessings up to the hall and share the marriage bed. The image fuses political security with conjugal intimacy: the nation is stabilized by bonds as inseparable as the one-eyed fish that must pair to see. From Fellowship to the Joyous, the transformation brings this union to its emotional peak. Paired lakes in the Joyous; friends study and discuss together. Joy arises from complementarity — two halves that complete each other, whether in the state, in the household, or between the doubled lakes of shared delight.
