Matsya Purana — Saubhagya-Śayana Vow: Lalitā/Gaurī–Śiva Worship
स्त्री भक्ता वा कुमारी वा शिवमभ्यर्च्य भक्तितः व्रतान्ते शयनं दद्यात् सर्वोपस्करसंयुतम् //
strī bhaktā vā kumārī vā śivamabhyarcya bhaktitaḥ vratānte śayanaṃ dadyāt sarvopaskarasaṃyutam //
Whether she is a devoted woman or an unmarried maiden, having worshipped Śiva with devotion, at the conclusion of the vow she should donate a bed furnished with all necessary accessories.
This verse does not address pralaya; it focuses on vrata-vidhi—how a Śiva vow should be concluded with an appropriate donation.
It reflects dharmic household practice: after completing a religious observance, one should perform dāna (charitable gifting). The specified gift—śayana-dāna—models responsible, compassion-oriented giving as part of vrata discipline.
Ritually, it prescribes a concluding gift: donating a fully furnished bed (śayana) with accessories, indicating that vows culminate in tangible charity (dāna) alongside worship (pūjā).
