Matsya Purana — Dhruva as Cosmic Pivot: Motions of Sun–Moon–Planets
ध्रुवेणाधिष्ठिताश्चापः सूर्यो वै गृह्य तिष्ठति सर्वभूतशरीरेषु त्व् आपो ह्यनुश्रिताश्च याः //
dhruveṇādhiṣṭhitāścāpaḥ sūryo vai gṛhya tiṣṭhati sarvabhūtaśarīreṣu tv āpo hyanuśritāśca yāḥ //
The Waters are upheld by Dhruva; and the Sun, having taken hold of that support, remains stationed. Indeed, the very Waters—those on which all embodied beings depend—are interwoven through the bodies of all creatures.
It presents the Waters (āpaḥ) as a fundamental cosmic support—linked to Dhruva and the Sun—implying that at Pralaya, when the cosmic order loosens, the waters that pervade beings and worlds become dominant again.
By stressing that water pervades all bodies and sustains life, it supports the dharmic priority of protecting water sources—wells, tanks, rivers, and irrigation—as a core royal duty and a householder’s daily ethic (non-waste, purity, and charitable water-giving).
Vāstu and ritual practice treat water as a life-supporting principle: siting and preserving tīrthas, wells, and temple tanks (puṣkariṇī) aligns built space with cosmic order, echoing the verse’s idea that waters are foundational and pervasive.
