Matsya Purana — Questions on Padmanabha’s Lotus-Creation in the Padma Mahakalpa; Prelude to N...
*मनुरुवाच कथं पाद्मे महाकल्पे तव पद्ममयं जगत् जलार्णवगतस्येह नाभौ जातं जनार्दन //
*manuruvāca kathaṃ pādme mahākalpe tava padmamayaṃ jagat jalārṇavagatasyeha nābhau jātaṃ janārdana //
Manu said: “O Janārdana, in the great Lotus-aeon (Pādma Mahākalpa), how did this lotus-formed universe of Yours arise here from the navel of You who were abiding in the oceanic waters?”
It frames re-creation after cosmic inundation: Vishnu abides in the cosmic waters (jalārṇava), and the lotus-linked emergence of the universe is questioned as the mechanism of renewed creation.
Indirectly, it models dharmic inquiry: Manu, the archetypal lawgiver-king, seeks the cosmic origin to ground right governance and household life in a correct understanding of time-cycles (kalpa) and divine order.
No explicit Vāstu or ritual rule is stated, but the lotus (padma) is a key sacred design archetype later used in temple plans and iconography; this verse supplies the cosmological symbolism behind “padma” patterns in Purāṇic sacred architecture.
