Matsya Purana — War of Devas and Asuras; Birth of Aurva Fire; Countering Tamasī Māyā through ...
पुरा ब्रह्मर्षिजः शक्र तपस्तेपे सुदारुणम् ऊर्वः सपूर्वतेजस्वी सदृशो ब्रह्मणो गुणैः //
purā brahmarṣijaḥ śakra tapastepe sudāruṇam ūrvaḥ sapūrvatejasvī sadṛśo brahmaṇo guṇaiḥ //
In former times, O Śakra, the Brahmarṣi Ūrva performed exceedingly fierce austerities—radiant with primeval splendor and comparable to Brahmā in his qualities.
This verse does not describe Pralaya directly; it highlights tapas (austerity) as a cosmic force that can elevate a sage to Brahmā-like stature, a theme often used in Purāṇas to explain shifts in power across cycles.
By praising severe discipline and virtue, the verse indirectly supports the Purāṇic ethic that rulers and householders should cultivate self-control, restraint, and dharmic conduct—tapas here functioning as the archetype of inner governance.
No specific Vāstu or temple rule is stated; the ritual takeaway is the primacy of tapas and spiritual qualification (guṇa) as the foundation for effective rites and religious authority.
