Matsya Purana — The Greatness of Prayaga and Allied Tirthas
इदं धन्यमिदं स्वर्ग्यम् इदं सत्यमिदं सुखम् इदं पुण्यमिदं धर्म्यं पावनं धर्ममुत्तमम् //
idaṃ dhanyamidaṃ svargyam idaṃ satyamidaṃ sukham idaṃ puṇyamidaṃ dharmyaṃ pāvanaṃ dharmamuttamam //
This is auspicious; this leads to heaven. This is truth; this is happiness. This is merit; this is righteous. This is purifying—the supreme Dharma.
This verse does not describe Pralaya directly; it functions as a doctrinal summary that elevates truth and righteousness as the “supreme Dharma,” the purifying principle that sustains order in any cosmic phase.
It frames governance and domestic life around satya (truth), dharma (righteous conduct), and puṇya (merit): a king protects society through truthful justice, while a householder cultivates happiness and purity through ethical, dharmic living.
No specific Vāstu or iconographic rule is stated; ritually, the verse serves as a general endorsement that dharmic, truthful acts are inherently “pāvana” (purifying), supporting the intent behind rites and sacred observances.
