今解：亦可定境非有非無名不可思議，諸佛境界亦爾，非有非無名不可思議，但以因中定境除執。依無性說：諸佛境界已永寂滅不依無性。

Present explanation: Alternatively, the object of samādhi being neither existent nor non-existent is called inconceivable; the sphere of the Buddhas is also like this—being neither existent nor non-existent, it is called inconceivable. However, because the object of samādhi on the causal stage removes attachment, it is spoken of based on non-nature; the sphere of the Buddhas is already eternally tranquil, so it is not based on non-nature.
