仁王經疏 1.334

1.334

釋曰：第二三無為空。文別有三：初標、次釋、後屬當。言得三無為者，總標。言智緣滅者，或名擇滅，擇謂智慧，由智斷障所得滅者，名為擇滅。非智緣滅者，亦名非擇滅。不由智力所得滅故，名非智緣滅，如前所說性淨涅槃等。言虛空者，即虛空無為。謂於真如上無色所現，義說名虛空。薩婆若果空，第三屬當。謂薩婆若果無為體上，義說三種。

Commentary: Second, the emptiness of the three unconditioned [dharmas]. The text has three parts: first, the proposition; next, the explanation; and finally, the attribution. The statement "attains the three unconditioned" is the general proposition. The phrase "cessation through wisdom-deliberation" is also called analytical cessation (pratisaṃkhyā-nirodha). "Deliberation" means wisdom; the cessation obtained through wisdom severing obstructions is named analytical cessation. "Cessation not through wisdom-deliberation" is also called non-analytical cessation (apratisaṃkhyā-nirodha). Because it is a cessation obtained not through the power of wisdom, it is named cessation not through wisdom-deliberation, like the previously mentioned nirvāṇa of natural purity and so forth. The word "space" refers to the unconditioned space (ākāśa-asaṃskṛta). This means that where form does not manifest upon tathatā, it is figuratively called space. "The fruit of sarvajñā is empty" is the third, the attribution. That is, upon the unconditioned essence of the fruit of sarvajñā, three kinds are figuratively expressed.
