羅剎娑（梵語也古云羅剎訛也羅字上聲呼兼彈舌引聲即正此乃暴惡鬼名也男即極醜女即甚姝美並皆食啖於人別有羅剎女國居海島之中如佛本行經中具說也）。

Rākṣasa (羅剎娑): A Sanskrit word. In ancient times it was called luóshà (羅剎), which is erroneous. The character luó (羅) should be pronounced in the rising tone together with a trilled tongue and a lengthened sound to be correct. This is the name of a violent and evil demon. The males are extremely ugly, while the females are exceedingly beautiful; both devour human flesh. There is separately a Kingdom of Rākṣasīs located on an island in the ocean, as fully explained in the Fo benxing jing (Abhiniṣkramaṇa-sūtra).
