三十七品是道場捨有為法故　此下三科約法明道場。什曰。道品斷受生故名捨有為。肇曰。三十七品無為之因也。又曰。無為即涅槃也。

"The thirty-seven bodhipakṣa dharmas are the bodhimaṇḍa, because one abandons conditioned dharmas." The following three sections explain the bodhimaṇḍa in terms of dharmas. Kumārajīva states: Because the bodhipakṣa dharmas sever the taking of rebirth, it is called abandoning the conditioned. Sengzhao states: The thirty-seven dharmas are the cause of the unconditioned. He also states: The unconditioned is nirvāṇa.
