I Ching Hexagram 34 – Dà Zhuàng (Great Strength)
Symbolic Meaning of the Dà Zhuàng Hexagram
The Dà Zhuàng (大壮) hexagram consists of two different trigrams stacked together. The lower trigram is Qián (乾), representing Heaven, while the upper trigram is Zhèn (震), representing Thunder. The imagery here is of thunder resounding in the sky, with rolling clouds and powerful reverberations. This symbolizes immense strength, robust vitality, and the flourishing of all things. The term “Zhuàng (壮)” means strength and vigor, and when combined with “Dà (大),” it signifies great and powerful strength, hence the name Dà Zhuàng.
