स्नातः शुक्लाम्बरस्तद्वद् यजमानो ऽभिपूजयेत् गोभिर् विभवतः सर्वान् ऋत्विजस्तान्समाहितः //
snātaḥ śuklāmbarastadvad yajamāno 'bhipūjayet gobhir vibhavataḥ sarvān ṛtvijastānsamāhitaḥ //
沐浴既毕并着白衣后,祭主(yajamāna)亦应以恭敬之礼供奉诸人;并当量力而行,心神安定、专注不散,以牛为施,敬赠一切执祭之祭官(ṛtvij)。
This verse does not address pralaya; it focuses on sacrificial etiquette—purity (bathing, white clothing) and proper honoring of priests with appropriate gifts.
It presents a core duty of the yajamāna (often a householder or ruler): maintain ritual purity and support the ṛtvij priests with dakṣiṇā—here, cows—given proportionate to one’s wealth, and offered with mental composure.
The significance is ritual, not architectural: the verse prescribes conduct for the sacrificer—post-bath purity, white attire, reverent honoring, and gifting cows as dakṣiṇā to the officiants.
