Matsya Purana — The Madana-Dvādaśī Vow and the Birth of the Maruts
यः कुर्याद् विधिनानेन मदनद्वादशीमिमाम् स सर्वपापनिर्मुक्तः प्राप्नोति हरिसाम्यताम् //
yaḥ kuryād vidhinānena madanadvādaśīmimām sa sarvapāpanirmuktaḥ prāpnoti harisāmyatām //
Whoever duly performs this Madana Dvādaśī observance according to the prescribed rite is freed from all sins and attains likeness—nearness in divine status—to Hari (Viṣṇu).
This verse does not discuss pralaya; it focuses on vrata-phala (the spiritual result of a Dvādaśī observance), emphasizing purification from sin and attaining closeness to Viṣṇu.
It frames ritual observance (vrata) as a practical dharmic duty: by following the prescribed method, a householder (and by extension a king setting public dharma) gains moral purification and Viṣṇu-oriented merit.
The significance is ritual rather than architectural: strict adherence to vidhi (prescribed procedure) in the Madana-Dvādaśī vow is presented as the key to its efficacy and spiritual attainment.
