Matsya Purana — Genealogy of Kaśyapa: Ādityas
पौलोमान्कालकेयांश्च मारीचो ऽजनयत्पुरा अवध्या ये ऽमराणां वै हिरण्यपुरवासिनः //
paulomānkālakeyāṃśca mārīco 'janayatpurā avadhyā ye 'marāṇāṃ vai hiraṇyapuravāsinaḥ //
In ancient times Marīci begot the Paulomas and the Kālakeyas—those dwellers of Hiraṇyapura who were indeed invincible to the gods.
It reflects the creation-side (sarga) genealogical expansion: Marīci’s lineage produces powerful Daitya/Dānava groups (Paulomas, Kālakeyas), indicating how cosmic history includes both divine and anti-divine lineages rather than focusing on Pralaya.
Indirectly, it supports the Purāṇic model of statecraft: rulers must understand lineages and the nature of hostile powers—here, clans described as “invincible to the Devas”—so a king’s dharma includes vigilance, alliances, and protection against formidable adversaries.
The verse hints at a famed fortified/urban realm—Hiraṇyapura (“Golden City”)—a motif later associated with powerful non-divine polities; while no Vāstu rule is stated here, it supplies the narrative backdrop for Purāṇic city-ideal themes relevant to Matsya Purana’s broader interest in settlement and sacred geography.
