Hexagram 51 — 震 (Zhèn), Thunder / Shock
Above: ☳ 震 Thunder Below: ☳ 震 Thunder
The Judgment
亨。震来虩虩，笑言哑哑。震惊百里，不丧匕鬯。
Thunder doubles — the shock that makes one tremble also brings the laughter of composure; the steady hand does not drop the ritual spoon.
The Image (Daxiang)
「洊雷，震；君子以恐惧修省。」Thunder doubled — the noble person turns fright into self-examination.—— 《周易·大象传》（The Image Commentary）
The Tuan Commentary
彖曰：震，亨。震来虩虩，恐致福也。笑言哑哑，后有则也。震惊百里，惊远而惧迩也。出可以守宗庙社稷，以为祭主也。——《易传·彖传》

Shockwave — stay composed and you'll laugh after. When you receive this hexagram, hold the judgment beside your question: it describes a posture and a season, not a script.
