Srimad-Bhagavatam: Canto 8 - Chapter 1 - Verse 5
कालेन पञ्चत्वमितेषु कृत्स्नशोलोकेषु पालेषु च सर्वहेतुषु ।तमस्तदासीद् गहनं गभीरंयस्तस्य पारेऽभिविराजते विभु: ॥ ५ ॥
kālena pañcatvam iteṣu kṛtsnaśolokeṣu pāleṣu ca sarva-hetuṣutamas tadāsīd gahanaṁ gabhīraṁyas tasya pāre ’bhivirājate vibhuḥ
In due course of time, when all the causative and effective manifestations of the universe, including the planets and their directors and maintainers, are annihilated, there is a situation of dense darkness. Above this darkness, however, is the Supreme Personality of Godhead. I take shelter of His lotus feet.
From the Vedic mantras we understand that the Supreme Personality of Godhead is above everything. He is supreme, above all the demigods, including Lord Brahmā and Lord Śiva. He is the supreme controller. When everything disappears by the influence of His energy, the cosmic situation is one of dense darkness. The Supreme Lord, however, is the sunshine, as confirmed in the Vedic mantras: āditya-varṇaṁ tamasaḥ parastāt. In our daily experience, when we on earth are in the darkness of night, the sun is always luminous somewhere in the sky. Similarly, the Supreme Personality of Godhead, the supreme sun, always remains luminous, even when the entire cosmic manifestation is annihilated in due course of time.
