Matsya Purana — Brahmā–Gāyatrī as a Divine Pair and the Early Genealogies of Creation
धन्या नाम मनोः कन्या ध्रुवाच्छिष्टम् अजीजनत् अग्निकन्या तु सुच्छाया शिष्टात्सा सुषुवे सुतान् //
dhanyā nāma manoḥ kanyā dhruvācchiṣṭam ajījanat agnikanyā tu succhāyā śiṣṭātsā suṣuve sutān //
Dhanyā, the daughter of Manu, bore a son named Chiṣṭa by Dhruva. And Succhāyā—said to be Agni’s daughter—then bore sons from that Chiṣṭa.
This verse does not describe Pralaya; it preserves post-creation social memory by listing Manu’s descendants and marital/parental links in the dynastic record.
Indirectly, it supports the Purana’s dharmic framework by emphasizing legitimate lineage and progeny—key concerns for householders (gṛhasthas) and royal succession in kingship traditions.
No Vastu/temple-architecture rule appears here; the verse is strictly genealogical, though such lineage sections often frame later ritual and royal-dharma instructions in the Purana.
