Matsya Purana — The Viśokā-Saptamī Vow
*ईश्वर उवाच विशोकसप्तमीं तद्वद् वक्ष्यामि मुनिपुंगव यामुपोष्य नरः शोकं न कदाचिदिहाश्नुते //
*īśvara uvāca viśokasaptamīṃ tadvad vakṣyāmi munipuṃgava yāmupoṣya naraḥ śokaṃ na kadācidihāśnute //
The Lord said: “O best of sages, I shall likewise describe the Viśoka-Saptamī. By fasting (upavāsa) on that sacred seventh lunar day, a person never experiences grief in this world.”
This verse does not discuss Pralaya; it introduces a vrata (Viśoka-Saptamī) focused on removing grief through disciplined fasting and sacred observance.
It frames upavāsa (fasting) as a practical dharmic discipline for laypeople: by observing prescribed vows, a householder (and by extension a ruler) cultivates steadiness, merit, and freedom from sorrow in worldly life.
The ritual significance is the naming and promise of the Viśoka-Saptamī vrata: fasting on the seventh lunar day is presented as a formal observance with a stated fruit—freedom from grief.
