師曠占曰。春雷始起其音柏柏格格。其霹靂者。所謂雄雷旱氣也。其鳴依音。音不大霹靂者。所謂雌雷水氣也。師曠占曰。春分雨雷有音。如雷非雷。音在地中。其所住者。兵起其下。無雲而雷名曰天狗。行不出三年其國凶。

The Divinations of Shi Kuang says: "When spring thunder first arises, its sound is bo-bo ge-ge. What crashes as a thunderbolt is the so-called male thunder, the vapour of drought. When its rumbling follows in low tones without great thunderbolts, that is the so-called female thunder, the vapour of water." The Divinations of Shi Kuang says: "When rain and thunder sound at the spring equinox, with a noise like thunder yet not thunder, and the sound is underground: wherever it dwells, warfare will arise beneath it. Thunder without clouds is named 'Heavenly Dog'; before three years pass, that state will suffer calamity."
