2.12

「云何眼等至說名有礙」者，此問礙義。云何眼等於自境界轉時說名有礙？此問境界有對。云何眼識等於自所緣轉時說名有礙？此問所緣有對。此中言自者，五根、五識各取自境，不能取他名自，非不為他緣。意、及意識緣法境故名自，非不能緣他。又解：緣十三界名自，非五根、五識取故。又解：十八界中隨所取者即名為自。

"How is it that the eye and the like ... are said to possess obstruction?" asks about the meaning of obstruction. How is it that when the eye and the like operate upon their own cognitive fields, they are said to possess obstruction? This asks about cognitive-field resistance. How is it that when eye-consciousness and the like operate upon their own objective supports, they are said to possess obstruction? This asks about objective-support resistance. Here, the word "own" means: the five sense-faculties and five consciousnesses each apprehend their own fields and cannot apprehend others, which is named "own," not that they cannot be grasped as objects by others. The manas and mental consciousness apprehend the dharma-field and are therefore named "own," not that they cannot apprehend others. Another explanation: apprehending the thirteen realms is named "own," because they are not apprehended by the five sense-faculties and five consciousnesses. Another explanation: among the eighteen realms, whatever is apprehended is immediately named "own".
