大般涅槃經義記 6.26

6.26

In 'unconditioned emptiness', it first asks, next explains, and finally summarizes and concludes. In the explanation, 'the unconditioned are all empty' generally marks it out. From 'Namely' below is the specific; in the specific there are three meanings, fully as explained above: first, within unconditioned emptiness there are no arbitrarily conceptualized sentient beings, life-spans, permanence, bliss, self, or purity—herein the substantial entity of unconditioned dharmas is not yet emptied; second, within this emptiness there are no internal or external affairs, nor conditioned dharmas; third, within this emptiness there is the meaning of the absence of Buddha, Dharma, Saṅgha, and buddha-nature.
