तत्प्रतिपादयति-एतत् शब्दसामान्यं हि यस्मात् शब्दविशे-षान् सर्वाणि नामानि बिभर्ति धारयति स्वरूपप्रदानेन ।एवं कार्यकारणत्वोपपत्तेः सामान्यविशेषोपपत्तेः आत्मप्रदा-नोपपत्तेश्च नामविशेषाणां शब्दमात्रता सिद्धा ।एवमुत्तर-योरपि सर्वं योज्यं यथोक्तम् ॥
In plain words
This is established: generic sound sustains all specific names by providing their very essence. Thus, because the relation of cause and effect, general and particular, and the bestowal of identity are all established, specific names are proven to be mere words. The same reasoning is to be applied to the remaining two [form and action] as already explained.
Close to the Sanskrit
That is established: because this generic sound sustains all particular names by bestowing their essential nature. Thus, through the establishment of the cause-effect relation, the relation of general and particular, and the granting of reality, the status of particular names as mere words is proven. Similarly, all should be applied to the remaining two as stated.
