ब्रह्मयोनौ प्रसूतस्य ब्राह्मणस्यात्मदर्शिनः ब्रह्मचर्यं सुचरितं ब्रह्माणमपि चालयेत् //
brahmayonau prasūtasya brāhmaṇasyātmadarśinaḥ brahmacaryaṃ sucaritaṃ brahmāṇamapi cālayet //
For a Brahmin—born from the source of Brahman, and a seer of the Self—well-practised brahmacarya (celibate student-discipline) is so potent that it can even shake Brahmā himself.
It does not describe pralaya directly; it emphasizes the cosmic potency of tapas—especially brahmacarya—so strong that it can metaphorically “shake” even Brahmā, implying ascetic power can influence cosmic order.
By highlighting brahmacarya as a source of spiritual authority, it supports the Rajadharma ideal that kings should honor disciplined Brahmins and protect ashrama-dharma; for householders, it underscores self-restraint as the foundation for ethical life and social stability.
No Vastu or temple-architecture rule appears here; the ritual takeaway is that strict brahmacarya is treated as a high-grade vow (vrata) generating exceptional spiritual force (tapas) relevant to rites, study, and purity.
