成唯識論演祕 2.195

問：身、語二表，經部、有宗俱非識變，何故身表而言識變即簡有宗，語表識變即簡經部？

Question: Regarding the two communicative actions of body and speech, neither the Sautrāntika nor the Sarvāstivāda maintains that they are transformations of consciousness. Why then does bodily communicative action, by being described as a transformation of consciousness, exclude the Sarvāstivāda, whereas vocal communicative action as a transformation of consciousness excludes the Sautrāntika?
