大般涅槃經義記 6.6

6.6

就前十中，初八以無破有為空，第九以有遣無為空，第十以其非有非無雙破有無名之為空，與《地經》中十平等同。

Within the first ten: the first eight take non-existence to refute existence as emptiness; the ninth takes existence to dispel non-existence as emptiness; the tenth, by neither existence nor non-existence, doubly refutes existence and non-existence, naming it emptiness; these are identical to the ten equalities in the Daśabhūmika Sūtra.
