Matsya Purana — Lineage of the Pitṛs
मेना च सुषुवे तिस्रः कन्या योगवतीस्ततः उमैकपर्णापर्णा च तीव्रव्रतपरायणाः //
menā ca suṣuve tisraḥ kanyā yogavatīstataḥ umaikaparṇāparṇā ca tīvravrataparāyaṇāḥ //
And Menā then gave birth to three daughters, all endowed with yogic power—Umā, Ekaparṇā, and Aparṇā—who were devoted to severe vows and austerities.
This verse does not discuss Pralaya; it focuses on sacred genealogy and the ascetic nature (tapas and vows) of Menā’s daughters, especially Umā’s forms.
Indirectly, it elevates the ideal of vrata (vowed discipline) and self-restraint—virtues praised for householders and rulers alike as foundations for dharma and moral governance.
No Vāstu or temple-building rule is stated here; the ritual takeaway is the prominence of tīvravrata (severe vows) and yogic discipline as sanctifying practices associated with the Goddess’ tradition.
