大般涅槃經義記 8.4

8.4

廣中，初先開列兩門，「從緣生貪」則為一門，明無淨性；「從緣心脫」復為一門，明無染性。次列二緣，先標後列，「隨於生死」是其染緣，「隨大涅槃」是其淨緣。下約二緣對貪明脫，四門辯之，先列後解。

In the broad explanation, first two gates are set out: "arising greed from conditions" is one gate, clarifying that it lacks a pure nature; "the mind being liberated from conditions" is another gate, clarifying that it lacks a defiled nature. Next, two conditions are listed, first designated and then listed: "conforming to saṃsāra" is the defiled condition; "conforming to Mahāparinirvāṇa" is the pure condition. Below, it clarifies liberation in relation to greed based on the two conditions, distinguishing it through four gates, first listing and then explaining them.
