नष्टे लोके द्विपरार्धावसाने महाभूतेष्वादिभूतं गतेषु । व्यक्तेऽव्यक्तं कालवेगेन याते भवानेक: शिष्यतेऽशेषसंज्ञ: ॥ २५ ॥

naṣṭe loke dvi-parārdhāvasāne mahā-bhūteṣv ādi-bhūtaṁ gateṣu vyakte ’vyaktaṁ kāla-vegena yāte bhavān ekaḥ śiṣyate ’śeṣa-saṁjñaḥ

mahā-bhūteṣu
when the five primary elements (earth, water, fire, air and ether)
ādi-bhūtam gateṣu
enter within the subtle elements of sense perception
vyakte
when everything manifested

into the unmanifested

After millions of years, at the time of cosmic annihilation, when everything, manifested and unmanifested, is annihilated by the force of time, the five gross elements enter into the subtle conception, and the manifested categories enter into the unmanifested substance. At that time, You alone remain, and You are known as Ananta Śeṣa-nāga.
