法華玄義釋籤 16.34

16.34

聲聞法中三種法印，廣說四種，略說一種。無常即是苦諦集諦，無我即是道諦，寂滅涅槃即是滅諦，是故衍中唯說諸法不生不滅一相無相，無相即是寂滅涅槃。

In the śrāvaka teachings, there are three kinds of dharma seals; explained broadly, there are four kinds, and explained briefly, there is one kind. Impermanence is precisely the truth of suffering and the truth of accumulation; non-self is precisely the truth of the path; quiescent extinction, nirvāṇa, is precisely the truth of cessation. Therefore, in the Mahāyāna, only that all dharmas are unarisen and unceasing, having a single mark that is markless, is spoken of; marklessness is precisely quiescent extinction, nirvāṇa.
