23.36

「上品忍無間至故名最勝」者，釋第十一句，於上忍後即生第一。如上品忍，緣苦諦行修一行，唯一剎那，有漏名世，勝故第一。能作等無間緣，有士用力，離同類因引聖道生，故名最勝。

Regarding 'Immediately after superior patience … therefore it is called supreme': this explains the eleventh line. Immediately after superior patience, the [worldly] supreme [dharmas] arise. Like superior patience, it takes the truth of suffering as its objective domain, cultivates a single aspect, and lasts only a single kṣaṇa; being sāsrava, it is called 'worldly', and because it is superior, it is 'supreme'. It can act as the immediately antecedent condition (samanantara-pratyaya), possessing virile activity (puruṣakāra), and, separated from homogeneous causes (sabhāga-hetu), induces the arising of the noble path; therefore it is called supreme.
