Matsya Purana — Origins of Gods and Beings: Daksha’s Progeny
ध्रुवस्य कालः पुत्रस्तु वर्चाः सोमादजायत द्रविणो हव्यवाहश्च धरपुत्राव् उभौ स्मृतौ //
dhruvasya kālaḥ putrastu varcāḥ somādajāyata draviṇo havyavāhaśca dharaputrāv ubhau smṛtau //
Dhruva’s son was Kāla. From Soma was born Varcas. And Draviṇa and Havyavāha are both remembered as the sons of Dharā.
This verse is genealogical and does not describe pralaya; it records lineages (vaṁśa) to preserve continuity of beings across cosmic ages.
Indirectly, it supports the Purāṇic ideal of dharma through lineage-memory: kings and householders are urged to maintain family continuity, honor ancestors, and preserve tradition through accurate genealogical remembrance.
No Vāstu or temple rule is stated here; the only ritual hint is the name Havyavāha (“carrier of oblations”), which evokes the sacrificial fire (Agni) as a cultural-religious backdrop rather than a technical instruction.
