The judgment
Legge
亨。震來虩虩,笑言啞啞。震驚百里,不喪匕鬯。
Shock intimates ease and development. When the time of movement which it indicates comes, the subject of the hexagram will be found looking out with apprehension, and yet smiling and talking cheerfully. When the movement like a crash of thunder terrifies all within a hundred miles, he will be like the sincere worshipper who is not startled into dropping his ladle and cup of sacrificial spirits.
