俱舍論疏 28.126

28.126

論「若爾正在定至成違理失」，有部難也。正在無漏定中，觸及身識應成無漏。以無漏初定現在前時，即以彼輕安觸是覺支。身識中樂為樂支，不可同五支中喜是無漏、樂是有漏，故成違理失。

On the treatise passage: "If so, while properly in absorption [...] it results in the error of contradicting reasoning": this is the Sarvāstivādin's objection. While properly in an anāsrava absorption, the tactile object and body-consciousness should become anāsrava. For when the anāsrava first absorption is present, that pliancy contact is a factor of awakening. If pleasure in body-consciousness is a factor of pleasure, it is impossible that among the same five factors, joy is anāsrava while pleasure is sāsrava; therefore it results in the error of contradicting reasoning.
