When the annihilation of the material elements is imminent, the Supreme Personality of Godhead in His form of eternal time withdraws the manifest cosmos, consisting of gross and subtle features, and the entire universe vanishes into nonmanifestation.
Srimad Bhagavata Purana

मूल श्लोकः
धातूपप्लव आसन्ने व्यक्तं द्रव्यगुणात्मकम् । अनादिनिधनः कालो ह्यव्यक्तायापकर्षति
dhātūpaplava āsanne vyaktaṃ dravyaguṇātmakam | anādinidhanaḥ kālo hyavyaktāyāpakarṣati
