Yilin Verse
長男少女，相向笑語；來歡致福，和悅樂喜。
An elder son and a young daughter face each other, laughing and talking; they bring joy and invoke blessing -- all is harmony and delight.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Earth above the lake erupts into thunder high in heaven — the exuberant strength of Great Power. The eldest son and youngest daughter face each other, exchanging smiles and playful words. They bring happiness and invite blessing; all is harmony and delight. The trigram pairing of Zhen (eldest son, thunder) and Dui (youngest daughter, lake) generates the warmth of intergenerational joy — youth and maturity in lighthearted exchange. From Approach to Great Power, the elder's measured oversight releases into vigorous celebration. Thunder above heaven is power at its most expansive, yet here it manifests not as domination but as familial warmth. Great strength exercised through gentleness — laughter between generations — is the most durable form of power.
