2.193

「生初靜慮至如理應思」者，此約此身生初定，約諸地明身、眼、色、識同異差別。如是若以三、四靜慮地眼，見自地色或下、上色者，以色望身說自、下、上。謂身生初定，以三、四定眼，見初定色名自，見欲界色名下，見二定已上色名上。若以色望眼，但有自、下，不得言上，以下地眼不見上色故。

Regarding the passage from "When born in the first dhyāna..." up to "should be considered according to the principle": 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 this body being born in the first dhyāna. As for seeing form of one's own stage, or lower, or higher form with the eye of the third or fourth dhyāna stages: one's own, lower, and higher are spoken of by matching the form against the body. That is, when the body is born in the first dhyāna, seeing form of the first dhyāna with the eye of the third or fourth dhyāna is called 'one's own'; seeing form of the desire realm is called 'lower'; seeing form of the second dhyāna and above is called 'higher.' If the form is matched against the eye, there are only 'one's own' and 'lower'; one cannot say 'higher,' because an eye of a lower stage cannot see form of a higher stage.
