Vaṃśānuvārṇana and the Transition to the Fourth (Upasaṃhāra) Pada
चतुर्युगसहस्रान्ते सर्वतः सलिलाप्लुते / सुषुप्सुरप्रकाशेप्सुः स रात्रिं कुरुते प्रभुः
caturyugasahasrānte sarvataḥ salilāplute / suṣupsuraprakāśepsuḥ sa rātriṃ kurute prabhuḥ
At the end of a thousand cycles of the four Yugas, when everything is flooded with water, the Lord, wishing to sleep and desiring no light, creates Night.
