大乘起信論義記 1.23

Question: Why do newly translated sūtras and śāstras say that there are those of the determinate two vehicles who enter cessation and do not turn their minds? Answer: In the new sūtras and śāstras, this is stated based on their definitely not turning their minds before entering cessation; they do not speak of what occurs after entering cessation, so there is no contradiction. Furthermore, teachings are distinguished into definitive and non-definitive, as distinguished in the Buddhadhātuśāstra; thus it is not surprising. Moreover, in the Nirvāṇasūtra, the statement 'those who speak of the existence or non-existence of buddha-nature do not understand my intention' clarifies that the dharma of buddha-nature is free from existence and free from non-existence; grasping onto it according to words is failing to understand the intention, and it does not mean teaching that a portion [of beings] lacks the nature. The Buddhadhātuśāstra states: 'Therefore, the buddha-nature is definitely existent, being free from existence and free from non-existence.' This is what it means. Therefore, all sentient beings are addressed by this [teaching], and other sūtras and śāstras should all be explained in accordance with this.
