ChU 6.3.4
तासां त्रिवृतं त्रिवृतम् एकैकाम् अकरोत् । यथा तु खलु सोम्येमास् तिस्रो देवतास् त्रिवृत् त्रिवृद् एकैका भवति तन् मे विजानीहीति
tāsāṃ trivṛtaṃ trivṛtam ekaikām akarot | yathā tu khalu somyemās tisro devatās trivṛt trivṛd ekaikā bhavati tan me vijānīhīti
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
'He made each of these tripartite; and how these three beings become each of them tripartite, that learn from me now, my friend!
