That conceptual cognition which has the appearance (nirbhāsa) of a non-existent, empty object — [such as] the conceptual cognition of imagined objects etc. [including] sky[-lotus] etc. — is called 'having the appearance of a non-existent object'. This [conceptual cognition of present objects] too is similar to that [in being] objectless — this is the meaning.
