Matsya-avatāra: The Lord as Fish Saves the Vedas and Guides Satyavrata
आसीदतीतकल्पान्ते ब्राह्मो नैमित्तिको लय: । समुद्रोपप्लुतास्तत्र लोका भूरादयो नृप ॥ ७ ॥
āsīd atīta-kalpānte brāhmo naimittiko layaḥ samudropaplutās tatra lokā bhūr-ādayo nṛpa
ഹേ രാജാവേ! കഴിഞ്ഞ കല്പാന്തത്തിൽ, ബ്രഹ്മാവിന്റെ ദിനാന്തത്തിൽ നൈമിത്തിക പ്രളയം സംഭവിച്ചു; അപ്പോൾ ഭൂഃ മുതലായ ലോകങ്ങൾ സമുദ്രജലത്തിൽ മുങ്ങിപ്പോയി।
This verse states that at the end of a kalpa there is a Brahmā-related, periodic dissolution in which the worlds beginning with Bhūrloka are submerged by ocean waters.
He is setting the cosmic background for the Matsya-avatāra narrative, explaining the conditions (a great inundation at kalpa’s end) in which the Lord’s protective pastime unfolds.
It cultivates detachment and urgency for bhakti—recognizing that worldly arrangements are temporary and that lasting shelter is found in devotion to the Lord.
