肇論新疏 3.64

3.64

然則有無絕於內、稱謂淪於外，視聽之所不暨（及）、四空之所昏昧，恬焉而夷（平）、怕然而泰（通），九流於是乎交歸、眾聖於是乎冥會，

Thus, existence and non-existence are cut off within, and appellations are submerged without; seeing and hearing do not reach it, and the four formless realms are benighted by it. Serene and level, tranquil and expansive, here the nine streams converge, and here the multitude of sages darkly unite.
