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
大王啊,在前一劫的终末、亦即梵天一日将尽之时,发生了“因时而起”的毁灭(naimittika pralaya);彼时从地界(Bhū)等诸世界皆为大海之水所淹没。
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.
