又樓炭經云。天下諸龍。以三熱見燒。阿耨達龍王。不以三熱見燒。一餘龍王熱沙雨身上。燒炙其痛。二餘龍王起婬相。向熱風來吹其身上燋。即失顏色。得此蛇身。便恐不喜。三餘龍王被金翅鳥食。悉皆恐怖。天下餘龍悉見毒熱。唯阿耨達龍王。獨不見熱。

Furthermore, the Loutan jing states: All nāgas under heaven are burned by the three heats. Only the Nāga King Anavatapta is not burned by the three heats. First, hot sand rains upon the bodies of the other nāga kings, scorching and torturing them with pain. Second, when other nāga kings give rise to lustful thoughts, a hot wind comes and blows upon their bodies, scorching them so that they immediately lose their normal form and assume this snake body, becoming fearful and unhappy. Third, other nāga kings are all terrified of being eaten by garuḍas. All the other nāgas under heaven experience poisonous heat; only the Nāga King Anavatapta alone does not experience heat.
