Matsya Purana — Description of Atri’s Hermitage: Sacred Grove Planning
क्वचिद्राजन्महिष्यश्च क्वचिदाजाश्च सर्वशः शिलाः क्षीरेण सम्पूर्णा दध्ना चान्यत्र वा बहिः //
kvacidrājanmahiṣyaśca kvacidājāśca sarvaśaḥ śilāḥ kṣīreṇa sampūrṇā dadhnā cānyatra vā bahiḥ //
In some places royal buffalo-cows are seen, and elsewhere goats are found on every side. In some places stones are found filled with milk, and elsewhere they are outwardly smeared or coated with curd (dadhi).
It presents unnatural, inverted phenomena (milk in stones, curd appearing externally) as portents—signals that cosmic and social order is destabilizing, a typical prelude to large-scale calamity such as pralaya.
Such anomalies function as warnings: a prudent king should treat them as indicators to restore dharma—through protection of subjects, ethical governance, and appropriate rites—rather than ignoring signs of disorder.
Ritually, milk and curd are auspicious substances; their impossible appearance in stones indicates a ‘misplacement of auspiciousness,’ prompting expiatory rites (śānti/pravṛtti of remedial rituals) rather than any direct Vastu rule.
