維摩經略疏 9.82

9.82

「現見」者，盡是二乘見思盡，不盡是凡夫生死無際。今觀盡不盡即是空，空不可盡、不可不盡，故言「癡如虛空不可盡，老死如虛空不可盡。」非盡不非盡中若作盡說，名畢竟空。若作不盡說，妙色湛然恒安住，不為生死之所遷。既非盡不盡則無二邊，得入不二之門。

"Direct Vision" (Pratyakṣadarśana): the exhausted is the exhaustion of views and thought by the two vehicles; the unexhausted is the boundless saṃsāra of ordinary beings. Now, contemplating the exhausted and the unexhausted as empty: emptiness cannot be exhausted and cannot be unexhausted; therefore it is said: "Ignorance is like space, inexhaustible; old age and death are like space, inexhaustible." If one speaks of exhaustion within what is neither exhausted nor unexhausted, it is called ultimate emptiness. If one speaks of non-exhaustion, wondrous form is serene and ever securely abiding, not shifted by saṃsāra. Since it is neither exhausted nor unexhausted, there are no two extremes, and one attains entry into the nondual door.
