ChU 4.14.1
ते होचुः । उपकोसलैषा सोम्य ते ऽस्मद्विद्यात्मविद्या च । आचार्यस् तु ते गतिं वक्तेति । आजगाम हास्याचार्यः । तम् आचार्यो ऽभ्युवादोपकोसल ३ इति
te hocuḥ | upakosalaiṣā somya te 'smadvidyātmavidyā ca | ācāryas tu te gatiṃ vakteti | ājagāma hāsyācāryaḥ | tam ācāryo 'bhyuvādopakosala 3 iti
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Then they all said: 'Upakosala, this is our knowledge, our friend, and the knowledge of the Self, but the teacher will tell you the way (to another life).'
