1 Gita Sloka  every day - Chapter 9 - Rajavidya Rajaguhya Yoga - Sloka 7

Krishna directing Creation

Sarva bhutani kaunteya prakritim yanti mamikam I

Kalpakshaye punah tani kalpa aadau visru jami aham II sloka 7

सर्व भूतानि कौन्तेय प्रकृतिं यन्ति मामिकाम् I
कल्पक्षये पुनः तानि कल्प आदौ विसृजामि अहं II श्लोक 7

All beings, O Kaunteya, go into my prakriti at the end of a kalpa. I generate them again at the end of the next kalpa.

When Brahma the creator goes to sleep it is the end of kalpa, extending into a thousand yugas. It works into an incalcul period ble crores of years of the human standard. Then the entire manifestation goes into the unmanifest state and remains dormant for an equally long period which is Brahma's night. When he wakes up again, the universe with the multitudinous beings come into manifestation. This is an eternal process.
