Bhagavad Gita Verse 8.19

हे पार्थ! वही यह भूतसमुदाय उत्पन्न हो होकर प्रकृतिके वशमें हुआ रात्रिके प्रवेशकालमें लीन होता है और दिनके प्रवेशकालमें फिर उत्पन्न होता है|

O Arjuna, all beings in this world, by the force of their nature, are born again and again, and dissolve repeatedly as well. They perish and join Brahma at the start of his night, and are born again at the start of his day.
