大般涅槃經義記 5.28

5.28

'Namely, attaining abiding in the initial immovable ground' generally clarifies the meaning of the accomplished immovability.

Below, it explains its marks: first it lists four gates; from 'like Sumeru' downward, it explains and interprets them in three turns, the text being clear and evident.
