大般涅槃經義記 6.37

6.37

上來十空與《地經》中十法平等其義相似，彼中初一總相明空，餘九是別。別中，初七以無破有，同此初八。彼中第八以有破無，同此第九。彼中後一以非有無雙破有無，同此空空。

The above ten emptinesses are similar in meaning to the equality of the ten dharmas in the *Daśabhūmika Sūtra*. There, the first one explains emptiness in general terms, and the remaining nine are specific. Among the specific ones, the first seven refute existence through non-existence, matching the first eight here. The eighth there refutes non-existence through existence, matching the ninth here. The last one there refutes both existence and non-existence through neither-existence-nor-non-existence, matching the emptiness of emptiness here.
