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.
