Yilin Verse
太公避紂，七十隱處。卒受聖文，為王室輔。
The Grand Duke avoids the tyrant Zhou, hiding for seventy years. At last he receives the sage King Wen and becomes the pillar of the royal house.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder over lake surges into thunder over heaven: the maiden's subordinate patience transforms into Great Power's thunderous authority. Taigong, the Grand Duke, fled the tyranny of King Zhou of Shang and lived in obscurity for seventy years. At last he received the sage King Wen's summons and became the pillar of the Zhou royal house. According to tradition, Jiang Ziya fished with a barbless hook by the Wei River, waiting for the right ruler to find him. From the Marrying Maiden to Great Power, thunder roars above heaven in irresistible force. The seventy years of hiding were not weakness but the accumulation of power that, when finally released, established a dynasty. Patience stored becomes thunder unleashed.
