高僧傳 9.24

9.24

At that time there was also a prolonged drought from the first month to the sixth month. Hu sent the Crown Prince to the west of Linzhang at Fukou to pray for rain, but after a long time none fell. Hu ordered Deng to go himself, and immediately two white dragons descended upon the site of the shrine. On that day there was heavy rain covering several thousand square li, and that year there was a great harvest. The Rong and Mo barbarians, who had previously not known the Dharma, heard of Deng's spiritual efficacy; they all bowed in worship from afar, and were transformed without words.
