俱舍論記 28.91

28.91

「如何無漏至少支無漏」者，說一切有部難。如何無漏靜慮現前，觸及身識樂少支有漏，意識相應少支無漏？此約體難。

Regarding the passage "How could [it be that in] an untainted... only a fraction of the factors is untainted?": The Sarvāstivāda objects: How could it be that when an untainted absorption is present, the tactile sensation and the pleasure of body-consciousness are a fraction of the factors that is tainted, while that associated with mental consciousness is a fraction of the factors that is untainted? This objects with regard to their substantial entity.
