肇論新疏 1.20

1.20

真謂真實。若法實有，有應無滅。法既隨滅，知非真有。下論云「夫有若真有，豈待緣而後有哉？《中觀》云：『法若實有，則不應無。』」等。

"Truly" means real. If dharmas truly existed, their existing should have no perishing. Since dharmas perish accordingly, we know they do not truly exist. The treatise below states: "Now if existence were true existence, how could it wait for conditions and only then exist?" The Mūlamadhyamakakārikā states: "If a dharma truly existed, it should not be non-existent," and so on.
