Yilin Verse
入天門，守地戶；居安樂，不勞苦。
Enter heaven gate, guard earth threshold; dwell in peace and joy, without toil or hardship.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder stirs the earth, and one enters the Gate of Heaven and guards the Door of Earth. Dwelling in peace and comfort, there is no toil or suffering. The verse is cosmological shorthand for occupying the pivotal nodes of the celestial-terrestrial axis — controlling both the entry point of divine energy and the stabilizing base of earthly foundation. This is not hermit's withdrawal but strategic positioning: holding the two poles of existence simultaneously. From Enthusiasm to The Wanderer, the transformation is paradoxical. The Wanderer moves through fire on a mountain, never settling. Yet the verse's subject has found stillness within perpetual transit — guarding heaven's gate and earth's door simultaneously, at home everywhere and therefore at peace while nominally wandering.
