經律異相 1.109

1.109

阿耨達龍王興大重雲。滿閻浮提並降大雨。百穀草樹皆悉滋長。江河川沼一切盈滿。此大雨水從龍王身心中出而能饒益無量眾生。摩那斯龍王將欲降雨。先興重雲彌覆虛空。慈悲心故凝停七日。先令眾生究竟諸業。漸降微雨普潤大地（出長阿含經第二十卷）。

The dragon king Anavatapta raises thick clouds filling Jambudvīpa and sends down heavy rain, so that the hundred grains, grasses, and trees all flourish and grow, and the rivers, streams, and ponds are all filled to overflowing. This great rainwater comes forth from the heart and mind of the dragon king, and is able to benefit countless sentient beings. When the dragon king Manasvin wishes to send down rain, he first raises thick clouds covering the sky; out of compassion, he holds them in place for seven days, first letting sentient beings finish their various tasks, and then gradually sends down gentle rain to moisten the whole earth. (From the Dīrgha-āgama, fascicle 20.)
