Yilin Verse
金柱鐵關，堅固衛災。君子居之，安無憂危。
Bronze pillars and iron bolts, firm and solid, warding off disaster. The noble man dwells within; peaceful, without worry or peril.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Heaven stored within the mountain yields to pure heaven doubled: all restraint gives way to unbroken strength. Gold pillars and iron gates stand firm, a fortress proof against disaster. The gentleman dwells within, secure and free from worry. Great Taming's image is accumulation — knowledge, virtue, resources held in reserve. When this stored power transforms into the Creative, the reserve becomes active defense. The verse celebrates the moment when accumulated strength crystallizes into impregnable structure. No attack can breach what has been built through patient taming. From Great Taming to the Creative, stored heaven breaks free of the mountain and stands as heaven alone — self-sustaining, self-protecting, needing nothing beyond its own cultivated strength.
