仁王護國般若波羅蜜多經疏 3.501

3.501

經：「四者時節改變，寒暑不恒，冬雨雷電、夏霜氷雪，雨土石山及以沙礫，非時降雹，雨赤黑水，江河汎漲，流石浮山。」

Sūtra: "Fourth is when the seasons alter: cold and heat are not regular; in winter there are rains, thunder, and lightning, and in summer frost, ice, and snow; showers of earth, stone mountains, sand, and gravel; unseasonable hail falls; rains of red and black water; rivers overflow in floods; and stones drift and mountains float."
