dragon kings [竜王] ( nāga-rāja; ryūō): Kings of the dragons said to live at the bottom of the sea. Eight dragon kings, each with many followers, are depicted in the Lotus Sutra assembling at the ceremony on Eagle Peak to hear the sutra taught. According to the Dragon King of the Sea Sutra, dragons are often eaten by giant birds called garudas, which are their natural enemies. See also dragon deity; eight great dragon kings.
