Matsya Purana — Dhruva as Cosmic Pivot: Motions of Sun–Moon–Planets
वाय्वाधारा वहन्ते वै सामृताः कल्पसाधकाः यान्यस्याण्डस्य भिन्नस्य प्राकृतान्यभवंस्तदा //
vāyvādhārā vahante vai sāmṛtāḥ kalpasādhakāḥ yānyasyāṇḍasya bhinnasya prākṛtānyabhavaṃstadā //
Supported by the Wind, they indeed move—endowed with a nectar-like sustaining power, accomplishing the ordering of an aeon (kalpa). At that time, from the splitting of this cosmic Egg, those primordial (prākṛta) constituents came into manifestation.
It frames creation as an emergence of prākṛta (primordial material) constituents when the cosmic Egg (brahmāṇḍa) splits, with Vāyu functioning as a sustaining support that helps the kalpa’s ordered manifestation proceed.
Indirectly, it presents a model of stability-through-support: just as Vāyu upholds cosmic functioning, a king upholds social order (dharma) and a householder upholds family and ritual continuity—each acting as a ‘support’ enabling orderly cycles rather than chaos.
No direct Vāstu or temple rule is stated, but the verse’s emphasis on ‘support’ (ādhāra) and ordered manifestation (kalpa-sādhana) aligns with Vāstu’s core idea: stable supports and correct arrangement are required for a structure (or rite) to remain life-sustaining and auspicious.
