Kāla-vibhāga: The Divisions of Time from Atom to Brahmā, and the Lord Beyond Time
त्रिलोक्या युगसाहस्रं बहिराब्रह्मणो दिनम् । तावत्येव निशा तात यन्निमीलति विश्वसृक् ॥ २२ ॥
tri-lokyā yuga-sāhasraṁ bahir ābrahmaṇo dinam tāvaty eva niśā tāta yan nimīlati viśva-sṛk
Fuera de los tres mundos (Svarga, Martya y Pātāla), en Brahmaloka, mil veces el ciclo de los cuatro yugas constituye un día de Brahmā. Un período igual es la noche de Brahmā, cuando el creador del universo cierra los ojos y duerme.
When Brahmā goes to sleep in his nighttime, the three planetary systems below Brahmaloka are all submerged in the water of devastation. In his sleeping condition, Brahmā dreams about the Garbhodakaśāyī Viṣṇu and takes instruction from the Lord for the rehabilitation of the devastated area of space.
