俱舍論記 27.8

27.8

「頌曰至於境無礙故」者，就頌答中，初六句出體；次兩句依地；次一句依處、依身；後一句釋力義。

On "The verse says: [...] because of unobstructedness regarding cognitive objects": In the answer through the verses: the first six lines state the essence; the next two lines deal with reliance on the stages; the next single line deals with reliance on the āyatanas and reliance on the body; the last single line explains the meaning of "power".
