泡炎（上普包反廣雅云泡流也說文水名也案經文幻泡炎則水上泡沫之類也亦隨雨滴而生者也遇風則滅俗謂之浮漚言動性無常如幻泡炎人之寄世有生亦滅不能堅久若此類也說文從水包聲下炎字讀與艷同）。

泡炎 ("bubbles and mirages"; the former character, fanqie: 普 + 包. The Guangya says: "Pao (泡) means flowing." The Shuowen says it is the name of a river. Examining the sūtra's phrase 'illusions, bubbles, and mirages,' it refers to foam upon water and the like, which also arises along with raindrops and vanishes upon meeting wind; popularly they are called floating froth. This speaks of the transient and unstable nature of things, like illusions, bubbles, and mirages: man's lodging in the world has birth and likewise destruction, unable to endure firmly, just like these. The Shuowen says: "It takes 水 as semantic and 包 as phonetic." The latter character yan (炎) is read the same as 艷).
