摩訶止觀 6.79

6.79

云何亦空亦有門？幻化見思雖無真實，分別假名則不可盡。如一微塵中有大千經卷；於第一義而不動；善能分別諸法相；亦如大地一，能生種種芽；無名相中，假名相說；乃至佛亦但有名字。是為亦有亦無門。

What is the gate of both emptiness and existence? Although the illusory [delusions of] view and thought lack reality, the distinctions of provisional designations are inexhaustible. It is like a great trichiliocosm's scroll of scriptures contained within a single speck of dust; remaining unmoved within the ultimate truth, one is well able to distinguish the characteristics of all dharmas. It is also like the single great earth being able to sprout various shoots; within what is free of names and characteristics, one speaks using provisional names and characteristics; up to the Buddha who also has only a name. This is the gate of both existence and non-existence.
