Matsya Purana — Phala-Saptamī Vow
सुरापानादिकं किंचिद् यदत्रामुत्र वा कृतम् तत्सर्वं नाशमायाति यः कुर्यात्फलसप्तमीम् //
surāpānādikaṃ kiṃcid yadatrāmutra vā kṛtam tatsarvaṃ nāśamāyāti yaḥ kuryātphalasaptamīm //
Whatever sin—such as drinking liquor—has been committed here (in this life) or elsewhere (in another existence), all of it comes to destruction for the one who performs the Phala-saptamī observance.
This verse is not about cosmic dissolution (Pralaya); it speaks of the ‘destruction’ of personal sin through the religious observance called Phala-saptamī.
It frames a practical dharma guideline: rulers and householders who may have incurred serious faults (e.g., surāpāna) are directed toward vrata-based purification, emphasizing ethical self-restraint and ritual discipline.
The significance is ritual rather than architectural: performing the Phala-saptamī vrata is presented as a powerful expiatory practice that nullifies grave sins.
