Bhagavad Gita 9.7

सर्वभूतानि कौन्तेय प्रकृतिं यान्ति मामिकाम्।कल्पक्षये पुनस्तानि कल्पादौ विसृजाम्यहम् ॥९.७॥

sarvabhūtāni kaunteya prakṛtiṃ yānti māmikāmkalpakṣaye punastāni kalpādau visṛjāmyaham

All beings, O Arjuna, go into My Nature at the end of a Kalpa; I send them forth again at the beginning of the next Kalpa.
