29.82

謂十二有支至亦都不可得者，釋前有因法也。十二有支，蘊、處、界三，此一切法唯有因果，無數取趣。但有情身無數取趣，即是內空。外非情法，亦復法空。修此空觀，亦不可得。

From 'Namely, the twelve limbs of existence' up to 'Is completely unfindable' explains the aforementioned 'phenomena having causes'. The twelve limbs of existence, and the three—aggregates, sensory bases, and elements—all these phenomena are merely cause and effect, without any person (puruṣa). Merely the body of a sentient being lacks a person; this is internal emptiness. External, insentient phenomena are likewise empty of dharmas. The one who cultivates this contemplation of emptiness is also unfindable.
