Matsya Purana — Duties of the Four Āśramas and the Power of Mauna
धौतदन्तं कृत्तनखं सदा स्नातमलंकृतम् असितं सितकर्मस्थं कस्तं नार्चितुमर्हति //
dhautadantaṃ kṛttanakhaṃ sadā snātamalaṃkṛtam asitaṃ sitakarmasthaṃ kastaṃ nārcitumarhati //
Who would not be worthy to worship one who keeps the teeth clean, the nails trimmed, is always bathed and well-adorned—though dark in complexion, yet established in pure conduct and virtuous deeds?
This verse does not discuss Pralaya; it focuses on dharma in worship—external cleanliness and inner purity as qualifications for honoring the worthy.
It frames daily discipline (cleanliness, grooming, regular bathing) and, more importantly, pure conduct as marks of a respectable person—guiding householders and rulers to honor virtue rather than judging by appearance.
Ritually, it supports archana norms: the worshipper (and the honored person) should embody śauca (cleanliness) and śīla (good conduct), underscoring that inner purity validates outer ritual.
