大般涅槃經義記 5.164

5.164

下佛答之，述其所問即為答矣。文中有三：一總明如來虛空佛性非苦、集等，亦非彼諦而是其實；二「所言苦者為無常」下別釋如來虛空佛性非苦、集等，但是其實；三「復次真者即如來」下別釋如來虛空佛性非是彼諦，但是其實。

Below, the Buddha answers him; recounting his question serves as the answer. The text has three parts: First, it generally clarifies that the Tathāgata, space, and the buddha-nature are not suffering, origin, and so forth, nor are they those truths, but they are their reality. Second, from 'what is called suffering is impermanent' below, it distinctly explains that the Tathāgata, space, and the buddha-nature are not suffering, origin, and so forth, but are only their reality. Third, from 'furthermore, the true is identical to the Tathāgata' below, it distinctly explains that the Tathāgata, space, and the buddha-nature are not those truths, but are only their reality.
