Matsya Purana — Vrata-Ṣaṣṭhī: The Sixty Sacred Vows
वत्सरं त्वेकभक्ताशी सभक्ष्यजलकुम्भदः शिवलोके वसेत्कल्पं प्राप्तिव्रतमिदं स्मृतम् //
vatsaraṃ tvekabhaktāśī sabhakṣyajalakumbhadaḥ śivaloke vasetkalpaṃ prāptivratamidaṃ smṛtam //
But if, for a year, one eats only a single meal a day and donates a water-pot together with provisions, one is said to dwell in Śiva’s world for a kalpa. This is remembered as the Prāpti-vrata (the vow that yields attainment).
This verse does not discuss pralaya; it teaches a dharma-based vrata promising residence in Śiva-loka as a karmic फल (result) of austerity and charity.
It frames household dharma as attainable through manageable discipline (one meal daily) and public-benefit charity (donating water with provisions), a model practice for householders and a king who sets ethical standards through dāna.
Ritually, it highlights jalakumbha-dāna (gift of a water-pot), a common Purāṇic charity linked to merit—especially valuable for travelers and ritual purity—rather than temple architecture rules.
