This is Gua 34 ䷡ in the Yi Jing, titled “Great Strength.” It is composed of ☳ Zhèn Thunder above ☰ Qián Heaven.
大壯
dà zhuàng
Robust, formidable, in full strength; great potency.
Meaning
A state of peak vigor or high magnitude of robustness; a flourishing vitality rather than mere physical size.
Grammar and usage
May function as an adjective describing a subject (formidable), a noun referring to a condition of maximum potency, or a dynamic indicator of expanding power.
Distinctions
Distinct from //lì// (力, physical force) or //qiáng// (強, stubborn strength/power) in its suggestion of holistic vitality.
Translator notes
In philosophical or divinatory contexts, the term often implies power in motion or vigorous expansion. This trajectory frequently signals a critical threshold where overwhelming force necessitates propriety and restraint to prevent recklessness; avoid reducing the term to a simple synonym for "strong" if the context suggests this tension between expansion and limit.
