tarka , m. (in Skt. reasoning, philosophizing ), as with Pali takka, in BHS seems normally to have pejorative connotation, sophistry, vain speculation ; typical are Sūtrāl. i.12 with comm. , see Léviʼs Transl. ( dialectique ), and Laṅk 24.2 kathaṃ hi śudhyate tarkaḥ kasmāt tarkaḥ pravartate, kathaṃ hi dṛśyate bhrāntiḥ …, how is tarka purified (got rid of)? From what does it arise?
