Matsya Purana — The Syamantaka Jewel Episode and the Vrishni–Sainya Genealogies
*सूत उवाच गान्धारी चैव माद्री च वृष्णिभार्ये बभूवतुः गान्धारी जनयामास सुमित्रं मित्रनन्दनम् //
*sūta uvāca gāndhārī caiva mādrī ca vṛṣṇibhārye babhūvatuḥ gāndhārī janayāmāsa sumitraṃ mitranandanam //
Sūta said: Gāndhārī and Mādrī became the wives of Vṛṣṇi. Gāndhārī gave birth to Sumitra, the delight of his friends.
Nothing directly—this verse is genealogical, recording marriages and offspring rather than cosmology or Pralaya.
It reflects the Purāṇic emphasis on lawful marriage and progeny as part of household (gṛhastha) order and the continuity of dynastic responsibility through heirs.
No Vāstu, temple-building, or ritual procedure is mentioned; the focus is purely on lineage and birth.
