Vaṃśānuvārṇana and the Transition to the Fourth (Upasaṃhāra) Pada
अथात्मनि महातेजाः सर्वमादाय सर्वकृत् / ततः स वसते रात्रिं तमस्येकार्णवे जले
athātmani mahātejāḥ sarvamādāya sarvakṛt / tataḥ sa vasate rātriṃ tamasyekārṇave jale
Then the mighty Radiant One, the Doer of all, gathers all into himself; thereafter he dwells through that night in the waters of the dark, single ocean—Ekārṇava.
