Matsya Purana — The Madana-Dvādaśī Vow and the Birth of the Maruts
ऊचुर् वसिष्ठप्रमुखा मदनद्वादशीव्रतम् यस्याः प्रभावादभवत् सुतशोकविवर्जिता //
ūcur vasiṣṭhapramukhā madanadvādaśīvratam yasyāḥ prabhāvādabhavat sutaśokavivarjitā //
Vasiṣṭha and the other sages said: “(She observed) the Madana-Dvādaśī vow; by the power of that vow, she became free from the grief caused by the loss of her son.”
This verse does not address pralaya or cosmology; it highlights the phala (spiritual effect) of a specific Dvādaśī vrata—removal of intense personal grief.
It supports the householder/kingly duty of maintaining dharma through vrata and niyama (disciplined observances), presenting ritual devotion as a means to restore emotional steadiness and righteous living after family tragedy.
The ritual significance is central: it names the Madana-Dvādaśī vrata and states its efficacy (prabhāva) in removing suta-śoka; no Vāstu or temple-construction rule is specified in this line.
