Matsya Purana — Iconographic Standards for the Navagrahas
रक्तमाल्याम्बरधरः शक्तिशूलगदाधरः चतुर्भुजः श्वेतरोमा वरदः स्याद् धरासुतः //
raktamālyāmbaradharaḥ śaktiśūlagadādharaḥ caturbhujaḥ śvetaromā varadaḥ syād dharāsutaḥ //
Dharāsuta should be depicted wearing a red garland and red garments, holding a spear (śakti), a trident, and a mace; four-armed, white-haired, and granting boons.
This verse does not discuss Pralaya; it gives iconographic specifications (color, arms, weapons, and boon-bestowing gesture) for depicting a deity called Dharāsuta.
Indirectly, it supports dharma through correct temple patronage: a king or householder should commission and worship properly formed images according to śāstric marks, ensuring ritually valid public and domestic worship.
It is a pratima-lakṣaṇa rule: the deity’s murti should be made with specific color symbolism (red attire/garland), four arms, and prescribed weapons (spear, trident, mace), with a varada (boon-giving) aspect—key for temple installation and consecration rites.
