Matsya Purana — The Strategy to Defeat Tāraka: Pārvatī’s Birth
विरहोत्कण्ठिता गाढं हरसंगमलालसा तयोः सुतप्ततपसोः संयोगः स्याच्छुभानने //
virahotkaṇṭhitā gāḍhaṃ harasaṃgamalālasā tayoḥ sutaptatapasoḥ saṃyogaḥ syācchubhānane //
Deeply anguished by separation, she longed intensely for union with Hara (Śiva). Then, O fair-faced one, the reunion of those two—whose austerities (tapas) had been well performed—came to pass.
This verse does not discuss Pralaya; it focuses on a mythic-emotional theme—separation (viraha), longing, and the auspicious reunion enabled by perfected austerity (tapas).
Indirectly, it reinforces a Matsya Purana ethical motif: disciplined effort (tapas/self-restraint) and fidelity to rightful bonds lead to auspicious reconciliation—values applicable to household harmony and responsible conduct.
No Vāstu or temple-building rule is stated here; the ritual takeaway is thematic—tapas (austerity/observance) is presented as a force that ripens circumstances toward auspicious union.
