俱舍論記 28.83

28.83

「有餘於此至為有何德」者，經部師通。有餘說一切有部師，於此經中增益心言，諸部經中唯說身故。又第三定所立樂支，契經自說為身所受樂故。汝說一切有部師，若謂於此經中說意為身。說意名身，為有何功德？

"Others in this regard... what benefit is there?" is the Sautrāntika master's resolution. Other Sarvāstivāda masters have added the word "mind" to this sūtra, for the sūtras of various schools speak only of "body." Furthermore, as for the factor of pleasure established in the third dhyāna, the sūtra itself states that it is "pleasure felt with the body." If you Sarvāstivādins claim that in this sūtra "mind" is spoken of as "body," what virtue or purpose is there in calling the mind "body"?
