12.139

又釋：言由體相故者，成上言說影像自性。及因性故者，成上造作影像自性。如是二種，都無所有也。此即約體性以辨無生觀為第六句。

Another explanation says: The phrase "due to substantial marks" establishes the aforementioned "intrinsic nature of images of verbal designation"; "and due to the nature of cause" establishes the aforementioned "intrinsic nature of fabricated images." These two types are entirely non-existent. This constitutes the sixth line, which delineates the contemplation of non-birth with respect to substantial nature.
