5.783

述曰：別釋有三：初正解頌文；次諍申同異；後顯果位是何性攝。初中又二，初解三性，名字隱故先解，是何謂無記性？謂三性中無記性也。何名俱非？顯彼自性非善、不善二種自性，故名俱非。釋無記名，下自別出。且何名為善？

It means the indeterminate nature among the three natures. Why is it called "neither"? It reveals that its intrinsic nature is neither of the two intrinsic natures, wholesome or unwholesome; therefore it is called "neither." The explanation of the name "indeterminate" is set forth separately below. For now, what is called "wholesome"?
