ChU 7.16.1
एष तु वा अतिवदति यः सत्येनातिवदति । सो ऽहं भगवः सत्येनातिवदतीति । सत्यं त्व् एव विजिज्ञासितव्यम् इति । सत्यं भगवो जिजिज्ञास इति
eṣa tu vā ativadati yaḥ satyenātivadati | so 'haṃ bhagavaḥ satyenātivadatīti | satyaṃ tv eva vijijñāsitavyam iti | satyaṃ bhagavo jijijñāsa iti
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
'But in reality he is an ativâdin who declares the Highest Being to be the True (Satya).' 'Sir, may I become an ativâdin by the True.' 'But we must desire to know the True.' 'Sir, I desire to know the True.'
Translated by F. Max Müller
