We have seen above that “conventional designation,” or that which is referred to by language, is one of the meanings of saṃvṛti [the empirical truth]. Reality is ultimately beyond adequate verbal expression, but we must communicate and “name” things and experiences if we are to live in this mundane world. The objects of our everyday experience can (according to Chih-i) be referred to as existing in the sense of arising interdependently. Our phenomenal world has temporary reality in the sense of an integrated, co-arising, interdependent relationship of causes and conditions. This is called “conventional” existence. One can also see that this is another way of making the same point as was made in the first two lines [All things which arise through conditioned co-arising / I explain as emptiness].
