大方廣佛華嚴經疏 54.8

54.8

Fourth, the two gates for the neither conditioned nor unconditioned dharmadhātu: 1. the gate of mutual negation through juxtaposition: meaning that conditions are never conditions devoid of noumenon, hence it is not conditioned; noumenon is never noumenon devoid of conditions, hence it is not unconditioned. The substance of dharmas being equal, juxtaposition completely extinguishes both. In chapter 39 of the *Pañcaviṃśatisāhasrikā*, Subhūti said to the Buddha: 'Is this equality of dharmas conditioned or is it unconditioned?' The Buddha said: 'It is not a conditioned dharma, nor is it an unconditioned dharma. Why is that? Apart from conditioned dharmas, unconditioned dharmas cannot be obtained; apart from unconditioned dharmas, conditioned dharmas cannot be obtained. Subhūti, this nature of the conditioned and nature of the unconditioned—these two dharmas neither combine nor disperse.' This is what it means. 2. The gate of having no resting place: meaning that this dharmadhātu is free from marks and free from nature, and therefore is not these two. Furthermore, because it is not the two truths, and because it is not what can be reached by the two designations, it is therefore neither. Fascicle 1 of the *Saṃdhinirmocana* states: 'All dharmas are briefly of two kinds, namely, conditioned and unconditioned. Therein, what is conditioned is neither conditioned nor unconditioned. What is unconditioned is neither unconditioned nor conditioned,' etc.
