Matsya Purana — Manvantaras
सेश्वराः स्वयमुद्भूता ब्रह्मणो मानसाः सुताः निवर्तमानैस्तैर्बुद्ध्या महान्परिगतः परः //
seśvarāḥ svayamudbhūtā brahmaṇo mānasāḥ sutāḥ nivartamānaistairbuddhyā mahānparigataḥ paraḥ //
Those mind-born sons of Brahmā—self-arisen and endowed with lordly powers—turned back; and by their awakened intelligence they comprehended the Supreme Great One who is beyond all.
It points to a cosmological-spiritual movement of withdrawal (nivartana/nivṛtti): even Brahmā’s primordial mind-born beings turn back from outward creation and, through refined intellect, realize the transcendent Supreme beyond the manifested order.
Indirectly, it frames the Purāṇic ideal that action (pravṛtti) should be guided by buddhi and culminate in discernment of the highest truth; for rulers and householders, this supports ethical governance and disciplined living oriented toward higher realization, not mere expansion of power.
No direct Vāstu or ritual rule is stated; the takeaway is conceptual—true ritual or sacred building is meant to support buddhi and inner withdrawal toward the Supreme (para), aligning external practice with transcendent purpose.
