Matsya Purana — Measures of Time: Caturyuga Computation
ऐश्वर्येणाणिमाद्येन प्रभुशक्तिबलान्विताः श्रुतेन तपसा चैव ऋषींस्ते ऽभिभवन्ति हि //
aiśvaryeṇāṇimādyena prabhuśaktibalānvitāḥ śrutena tapasā caiva ṛṣīṃste 'bhibhavanti hi //
Endowed with sovereign power—such as aṇimā and the other extraordinary attainments—strengthened by mastery and might, and supported by sacred learning (śruti) and austerity (tapas), they indeed surpass even the sages (ṛṣis).
It does not describe pralaya directly; it emphasizes that in cosmic cycles, true superiority is achieved through aiśvarya (spiritual sovereignty) grounded in śruti and tapas, which can eclipse even revered ṛṣis.
It implies that authority should be rooted in discipline and learning: a ruler or householder gains legitimate “prabhu-śakti” through self-control (tapas) and adherence to sacred instruction (śruti), not merely by worldly force.
No explicit Vastu or temple rule appears; ritually, it highlights tapas and śruti as the enabling foundations for effective mantra, vrata, and higher attainments (siddhis) that support sacred practice.
