SB 8.3.5
kalena pañcatvam itesu krtsnaso
lokesu palesu ca sarva-hetusu
tamas tadasid gahanam gabhiram
yas tasya pare ’bhivirajate vibhuh
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
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.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
From the Vedic mantras we understand that the Supreme Personality of Godhead is above everything. He is supreme, above all the demigods, including Lord Brahma and Lord Siva. 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: aditya-varnam tamasah parastat. 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.
