The most mature and wise interpretation of the I Ching is:
Do not seek fortune or misfortune; rather, investigate the principles of Heaven, the Way, and the human heart.
Today, we examine Hexagram 42 — Yì (Wind over Thunder / Increase), exploring its inner principles, life guidance, six-line meanings, and practical applications.
I. Overview of Yì — “Reduce the Excess Above, Benefit Below, Serve the World”
Hexagram: Wind over Thunder (Upper Xùn / Lower Zhèn)
Lower trigram: Zhèn ☳ (Thunder) — active, vigorous, capable of movement
Symbolism: Wind over thunder symbolizes the exchange of energy, growth of all things, and boundless blessings.
This is the essence of Yì: increase, benefit, nourishment, growth, mutual advantage.
Judgment:
Yì: Beneficial to proceed; beneficial to cross the great river.
Meaning: “Yì” refers to benefit, growth, and increase.
In accordance with natural principles: where things move smoothly, benefit arises; where things resist, loss occurs.
Acting with virtue, helping others, and sincerity ensures success.
Image:
Wind over thunder: the noble person sees good and follows it, sees error and corrects it.
Highest principle: Benefit oneself by benefiting others — “mutual increase.”
Core Spirit:
Yì is the hexagram of self-benefit through benefiting others, the path of mutual advantage.
At the level of Heaven: reduce excess above, increase below; maintain balance.
At the social level: use resources wisely, help the weak, strengthen mutual support.
At the personal level: benefit oneself by benefiting others.
True benefit flows with Heaven; damage flows against Heaven.
Genuine increase is not self-serving, but aligned with the greater Way.
