Matsya Purana — Manvantaras
निवृत्तिसमकालाच्च बुद्ध्याव्यक्त ऋषिस्त्वयम् ऋषते परमं यस्मात् परमर्षिस्ततः स्मृतः //
nivṛttisamakālācca buddhyāvyakta ṛṣistvayam ṛṣate paramaṃ yasmāt paramarṣistataḥ smṛtaḥ //
And because you arise at the very time of withdrawal (nivṛtti), you are a Ṛṣi whose intelligence is unmanifest (avyakta). Since you attain the supreme state of ṛṣi-hood, you are therefore remembered as a Paramarṣi.
It points to a pralaya-adjacent idea: at the moment of nivṛtti (withdrawal/cessation), a seer’s cognition becomes subtle (avyakta), indicating an inward turning that aligns with dissolution-oriented spirituality rather than outward creation.
It frames an ideal end-goal for rulers like Manu: even while upholding dharma, one should cultivate nivṛtti (inner renunciation) so that wisdom becomes steady and subtle—leading toward the highest spiritual status rather than mere worldly sovereignty.
No direct Vāstu or ritual procedure is stated; the takeaway is conceptual: successful rites and sacred building are meant to support nivṛtti—inner withdrawal and refinement of buddhi—culminating in higher spiritual realization.
