觀無量壽佛經疏 2.26

2.26

二、從有一太子下，至惡友之教已來，正明闍王怳忽之間，信受惡人所誤。言太子者，彰其位也。言阿闍世者，顯其名也。又阿闍世者乃是西國正音，此地往翻，名未生怨，亦名折指。

Second, from “There was a crown prince” down to “following the instruction of an evil friend,” it directly explains that in a state of confusion and delusion, King [Ajātaśatru] placed faith in and accepted the deception of an evil person. The word “crown prince” clarifies his rank. The name “Ajātaśatru” reveals his name. Moreover, “Ajātaśatru” is the correct pronunciation from the Western Regions; previously translated here, it means “Unborn Enmity” and is also called “Broken Finger.”
