注大乘入楞伽經 7.143

7.143

夫方便教說有無者，相形待而生故。為遣執有故言無，遣墮無故言有。若言法身超一切量，無既不可取，有豈容言說？

When the expedient teachings speak of existence and non-existence, it is because they arise in mutual dependence. To dispel the grasping at existence, non-existence is taught; to dispel falling into non-existence, existence is taught. If one says that the Dharmakāya transcends all measures, since non-existence cannot be grasped, how could existence ever be spoken of?
