19. That (perception) is necessary due to the delusion (moha) of right vision, but it is not intrinsically real. From a thorough consideration of things as they truly are, both agency (kartṛtva) and enjoyership (bhoktṛtva) do not exist. Perceptions such as aversion and desire regarding the senses and their objects are seen by those who possess such views, but not by those who do not.
