Matsya Purana — Ritual Bathing
सप्तवाराभिजप्तेन करसम्पुटयोजितः मूर्ध्नि कुर्याज्जलं भूयस् त्रिचतुष्पञ्चसप्तकम् स्नानं कुर्यान्मृदा तद्वद् आमन्त्र्य तु विधानतः //
saptavārābhijaptena karasampuṭayojitaḥ mūrdhni kuryājjalaṃ bhūyas tricatuṣpañcasaptakam snānaṃ kuryānmṛdā tadvad āmantrya tu vidhānataḥ //
Having recited (the mantra) seven times, and cupping the hands together, one should pour water again and again upon the crown of the head—three, four, five, or seven times. In the same manner one should bathe with purifying earth (clay), duly invoking it according to the prescribed rule.
This verse is not about Pralaya; it gives practical śauca (purification) instructions—mantra-charged water poured on the head and bathing with consecrated earth—showing how dharma is maintained through ritual purity rather than describing cosmic dissolution.
It prescribes disciplined daily purification (snāna with mantra and mṛdā), a core duty for householders and rulers alike before worship, gifts, rites, or governance—implying that personal purity supports ethical action and public dharma.
Ritually, it specifies counted ablutions (3/4/5/7) and the use of invoked purifying earth—procedural details often required before temple entry, image worship, or Vastu-related consecrations where purity is a prerequisite.
