Line 1
初九
震來虩虩,後笑言啞啞,吉。
Shock arrives with fear; afterward, speech and laughter return. Favorable.
Fear is followed by laughter in Line 1, whose verdict is favorable. Its change makes Earth below Thunder, Hexagram 16. The contrast is between two Thunder trigrams and a single Thunder above Earth, setting repeated shock beside the theme of enthusiasm.
