涅槃經遊意 1.65

1.65

我今依經文自云：「無得者名大涅槃」，故無所得，此經宗也。又亦汝言涅槃定常不得無常，斯則常故，常名有所得；有所得者，乃名生死，何謂涅槃？

I now rely on the sūtra text which itself says: "Non-acquisition is named great nirvāṇa." Therefore, having nothing that is acquired is the central tenet of this sūtra. Furthermore, when you say that nirvāṇa is definitely permanent and cannot be impermanent, then because of this permanence, permanence is called having something that is acquired; and having something that is acquired is called saṃsāra—how can it be called nirvāṇa?
