Matsya Purana — Vrata-Ṣaṣṭhī: The Sixty Sacred Vows
दद्याद् विंशत्पलादूर्ध्वं महीं कृत्वा तु काञ्चनीम् दिनं पयोव्रतस्तिष्ठेद् रुद्रलोके महीयते धराव्रतमिदं प्रोक्तं सप्तकल्पशतानुगम् //
dadyād viṃśatpalādūrdhvaṃ mahīṃ kṛtvā tu kāñcanīm dinaṃ payovratastiṣṭhed rudraloke mahīyate dharāvratamidaṃ proktaṃ saptakalpaśatānugam //
Having fashioned a golden representation of the Earth weighing more than twenty palas, one should donate it; then, observing a milk-only vow for a day, one is honored in Rudra’s world. This observance is declared to be the Dharā-vrata, whose merit endures for seven hundred kalpas.
It does not describe Pralaya directly; instead, it emphasizes dharmic ritual merit—symbolically honoring the Earth through a golden offering and austerity, yielding long-lasting spiritual reward.
It presents a practical dharma act: charitable giving (dāna) combined with a brief austerity (one-day payo-vrata). Such rites are especially suited to householders and rulers who can sponsor gifts and uphold religious observances for societal and personal merit.
Ritually, it prescribes making a gold ‘Earth’ (mahī) of specified minimum weight (over twenty palas) as a formal donation, followed by a milk-only fast—an example of precise vrata-vidhi typical of the Matsya Purana’s ritual manuals.
