《大象》：洊雷，震；君子以恐懼脩省。 ｜ 《彖传》：震，亨。震來虩虩，恐致福也。笑言啞啞，後有則也。震驚百里，驚遠而懼邇也。出可以守宗廟社稷，以為祭主也。

Its Polarity Opposite (Cuo Gua · 错卦) is #57 巽 (Subtle Persistent Influence), its Overturned Inverse (Zong Gua · 综卦) is #52 艮 (Meditative Stillness), and its Nuclear Core (Hu Gua · 互卦) reveals #39 蹇 (Recalibrating Before Obstacles).
