摩訶止觀 5.229

5.229

今推此塵為是心故生心？為非心故生心？塵若是心，則不名塵，亦非意外，則同自生。又二心並，則無能所。塵若非心，那能生心？如前破。若塵中有生性，是故生心；此性為有？為無？性若是有，性與塵並，亦無能所；若無，無不能生。如是推求，知心畢竟不從塵生。

Now we investigate whether this object generates mind because it is mind, or generates mind because it is not mind. If the object is mind, it is not called an object, nor is it outside the mind, and thus it is the same as self-generation. Furthermore, if two minds exist side by side, there is neither generator nor generated. If the object is not mind, how could it generate mind? As refuted earlier. If there is a generative nature within the object and it therefore generates mind: is this nature existent or nonexistent? If the nature is existent, nature and object exist side by side, and there is also neither generator nor generated; if nonexistent, what is nonexistent cannot generate. Investigating in this manner, one knows that mind ultimately does not arise from objects.
