Matsya Purana — Cosmic Architecture of Sun–Moon and the ‘Houses of the Gods’
विस्तारमण्डलाभ्यां तु पादहीनस्तयोर्बुधः तारानक्षत्ररूपाणि वपुष्मन्तीह यानि वै //
vistāramaṇḍalābhyāṃ tu pādahīnastayorbudhaḥ tārānakṣatrarūpāṇi vapuṣmantīha yāni vai //
But Budha (Mercury), within those circular diagrams of measure and extent, is to be fashioned “without feet”; for the forms of the stars and constellations described here are embodied, iconic forms.
This verse does not discuss Pralaya; it focuses on iconographic specification—how Budha (Mercury) and star/nakshatra forms are to be represented in mandala-based design.
Indirectly, it supports dharmic patronage: kings and householders who commission temples and images should follow śāstric standards (here, correct celestial iconography) to ensure ritual propriety and auspiciousness.
It gives a pratima-lakshana rule tied to mandala measurements: Budha’s form is prescribed as ‘footless’ within the iconographic/mandala scheme, guiding sculptors and temple artists in compliant depiction.
