Matsya Purana — Dhruva as Cosmic Pivot: Motions of Sun–Moon–Planets
मेहनाच्च मिहेर् धातोर् मेघत्वं व्यञ्जयन्ति च न भ्रश्यन्ते ततो ह्यापस् तस्मादभ्रस्य वै स्थितिः स्रष्टासौ वृष्टिसर्गस्य ध्रुवेणाधिष्ठितो रविः //
mehanācca miher dhātor meghatvaṃ vyañjayanti ca na bhraśyante tato hyāpas tasmādabhrasya vai sthitiḥ sraṣṭāsau vṛṣṭisargasya dhruveṇādhiṣṭhito raviḥ //
And from the verbal root miha, meaning “to pour forth, to shed moisture,” they also indicate the condition of being a cloud (megha-hood). Therefore the waters do not fall down at once; hence the cloud indeed remains suspended. The Sun (Ravi), established and supported by Dhruva, the Fixed Point, is the producer of the creation of rainfall.
It focuses on ongoing cosmic regulation rather than Pralaya: waters are held in clouds and released as rain under the Sun’s agency, showing an ordered mechanism sustaining the world between dissolutions.
By presenting rain as a divinely regulated process, it underlines the king’s duty to protect agrarian welfare (food, water, seasons) and the householder’s dependence on seasonal rains for yajña, crops, and daily sustenance.
Ritually, it supports rain-invoking and seasonal rites by linking rainfall to solar order; architecturally, it indirectly reinforces Vāstu’s emphasis on solar directionality and cosmic alignment (Dhruva as a fixed axis) when orienting sacred and domestic spaces.
