त्रयोदशैते विज्ञेया ब्रह्मिष्ठाः कौशिका वराः अगस्त्यो ऽथ दृढद्युम्न इन्द्रबाहुस्तथैव च //
trayodaśaite vijñeyā brahmiṣṭhāḥ kauśikā varāḥ agastyo 'tha dṛḍhadyumna indrabāhustathaiva ca //
ఈ పదమూడు మంది శ్రేష్ఠ కౌశిక బ్రహ్మిష్ఠులు (బ్రహ్మనిష్ఠ ఋషులు) అని తెలిసికొనవలెను—అగస్త్యుడు, దృఢద్యుమ్నుడు, అలాగే ఇంద్రబాహుడు.
This verse does not discuss Pralaya; it functions as a genealogical/catalogue statement identifying a set of thirteen Brahman-established sages within the Kauśika lineage.
Indirectly, it supports the Purāṇic ideal that rulers and householders should honor and seek guidance from brahmiṣṭha sages—those established in Brahman—since such lineages preserve dharma, ritual correctness, and ethical counsel.
No Vāstu or temple-building rule is stated here; the ritual takeaway is the emphasis on brahmiṣṭha rishis as authoritative transmitters of sacred knowledge and proper practice.
