俱舍論記 2.192

2.192

「應言此四至如理應思」者，答。此約身生欲界，約諸地明身、眼、色、識同異差別。

Regarding the passage from "One should say that these four..." up to "should be considered according to the principle": This is the answer. This explains the differences of identity and difference among the body, the eye, the form, and the consciousness across the various stages, with reference to the body being born in the desire realm.
