Matsya Purana — War of Devas and Asuras; Birth of Aurva Fire; Countering Tamasī Māyā through ...
ब्रह्मचर्ये स्थितं सत्यं ब्रह्मचर्ये स्थितं तपः ये स्थिता ब्रह्मचर्ये तु ब्राह्मणा दिवि संस्थिताः //
brahmacarye sthitaṃ satyaṃ brahmacarye sthitaṃ tapaḥ ye sthitā brahmacarye tu brāhmaṇā divi saṃsthitāḥ //
Truth is established in brahmacarya (celibate discipline); austerity too is established in brahmacarya. Those brāhmaṇas who remain steadfast in brahmacarya become firmly established in heaven.
This verse does not address pralaya directly; it teaches that moral and spiritual potency—truthfulness and austerity—are stabilized through brahmacarya, a principle that supports cosmic order (dharma) rather than describing dissolution.
While aimed at brāhmaṇas and the brahmacarya ideal, it guides kings and householders indirectly: governance and family life thrive when leaders uphold satya (truth) and tapas (self-restraint). Even without formal celibacy, disciplined control of senses is presented as the root of ethical authority.
No vastu or temple-building rule is stated here; ritually, it implies that vows of continence and self-restraint strengthen truthfulness and austerity, which are foundational qualifications for effective mantra-japa, yajña performance, and priestly integrity.
