肇論新疏 2.365

2.365

故經云：「般若於諸法無取無捨，無知無不知。」此攀緣之外、絕心之域，而欲以有無詰者，不亦遠乎。

Therefore the sūtra says: "Prajñā neither grasps nor abandons any dharmas; it is without knowing, yet there is nothing it does not know." This lies beyond object-grasping and is the realm where the mind is cut off; to wish to interrogate it in terms of existence and non-existence—is that not far wide of the mark?
