俱舍論記 1.224

1.224

「若言相待麁細不成」者，此難不然。觀待異故，故成麁、細。猶如父子、苦集諦等，雖是一物，所望不同，得名父子、苦集諦等。問：麁、細相待對立一法說麁細。亦可長、短相待對一體相形立。解云：色處簡差別，長、短別有體；麁、細通五蘊，不可例長短。

"If you say relative, coarse and subtle would not be established": this objection is not correct. Because of the difference in perspective, coarse and subtle are established. Just like father and son, or the truths of suffering and origin, etc., although it is a single thing, depending on what it is viewed against, it obtains the names "father", "son", "truth of suffering", "truth of origin", and so forth. Question: Coarse and subtle are established relatively by viewing a single dharma as coarse or subtle. Could long and short also be established relatively by comparing a single substance? Explanation: The matter base distinguishes differences, and long and short have separate substances; coarse and subtle apply across all five skandhas, and cannot be analogized to long and short.
