金光明經文句記 4.74

4.74

First, directly showing the three propositions. Regarding the eighteen kinds of emptiness and so on: the essence of emptiness is unique; it everywhere sweeps clean the various objects, and names are established in accordance with the objects. Just as fire is one, yet different names arise in accordance with the things it burns, so the meanings under the names cannot but differ. Therefore, because internal dharmas are eliminated, it is called internal emptiness; because external dharmas are eliminated, it is called external emptiness. Eliminating eighteen objects is called the eighteen kinds of emptiness; the twenty kinds of emptiness and twenty-four kinds of emptiness are also like this. Hence, both name and meaning are extensive. Establishing the single name 'emptiness' exclusively expresses eradication and sweeping clean, so both name and meaning are brief. Terms such as 'Dharma-nature' have numerous established names, yet they only express the meaning of the original nature.
