Yilin Verse
入暗出明，動作有光；運轉休息，常樂允康。
Entering darkness, emerging into light; every action has its radiance. Turning and resting in rhythm, ever joyful and at ease.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder rests within the lake, and the journey moves from darkness into light. Actions shine with radiance; the cycle of effort and rest turns smoothly, bringing constant joy and abiding health. The verse is an unusually pure benediction — no danger, no irony, simply the natural rhythm of labor and repose producing wellbeing. From Following to the Abysmal, the paradox is striking: Kan represents doubled peril, water upon water, yet this verse finds within that repeated descent a rhythm of renewal. Entering darkness and emerging into light is precisely the Abysmal's discipline: one who follows the water's way — flowing through danger without resisting — discovers that the abyss itself teaches constancy.
