涅槃經遊意 1.15

1.15

涅槃之法竟何所有？雖無所有而無所不有，雖無所不有而無所有。有無既爾，常無常亦然，非常非無常，常無常具足也。

What, in the end, does the dharma of nirvāṇa have? Although it has nothing, there is nothing it does not have; although there is nothing it does not have, it has nothing. Since existence and nonexistence are like this, permanence and impermanence are also like this: it is neither permanent nor impermanent, yet permanence and impermanence are fully complete.
