Bhagavad Gita · 8.19

भूतग्रामः स एवायं भूत्वा भूत्वा प्रलीयते।रात्र्यागमेऽवशः पार्थ प्रभवत्यहरागमे॥

bhūta-grāmaḥ sa evāyaṁ bhūtvā bhūtvā pralīyate rātry-āgame 'vaśhaḥ pārtha prabhavaty ahar-āgame

That same multitude of beings, coming into existence again and again, is dissolved at the fall of night, O Partha, and comes forth helplessly at the arrival of day.
