नासौ चित्तं ततश्चेत्यं यत्नतश्चेत्यते यया ॥ ५ ॥

evaṃ hi kāraṇābhāvāccetyasyāsaṃbhavāditi ,
nāsau cittaṃ tataścetyaṃ yatnataścetyate yayā 5

5. evaṃ hi kāraṇābhāvāt ca ity asya asaṃbhavāt iti
na asau cittaṃ tataḥ cetyaṃ yatnataḥ cetyate yayā

5. evaṃ hi kāraṇābhāvāt ca cetyasya asaṃbhavāt iti
asau cittaṃ na tataḥ cetyaṃ yayā yatnataḥ cetyate

5. Thus, indeed, due to the absence of a cause and the impossibility of an object of cognition (cetya), that (consciousness) is not the mind (citta). Consequently, it is not the cognized object (cetya) by which it (consciousness) is diligently cognized.
