Matsya Purana — Cosmic Architecture of Sun–Moon and the ‘Houses of the Gods’
लोहितो नवरश्मिस्तु स्थानमाप्यं तु तस्य वै बृहद्द्वादशरश्मीकं हरिद्राभं तु वेधसः //
lohito navaraśmistu sthānamāpyaṃ tu tasya vai bṛhaddvādaśaraśmīkaṃ haridrābhaṃ tu vedhasaḥ //
The red form (Lohita) has nine rays—this indeed is its proper placement. But the Creator, Vedhas (Brahmā), is vast, possessing twelve rays, and bears the hue of turmeric (golden-yellow).
It does not describe Pralaya directly; instead, it classifies divine forms by rays and color—an iconographic/astral taxonomy often used to express cosmic order maintained by the Creator.
By prescribing correct attributes (rays, hues, and placement), it supports dharmic patronage: kings and householders commissioning images or shrines should follow authoritative standards to ensure ritual correctness and auspicious results.
It specifies iconographic identifiers—number of rays and color—useful for temple image-making, mural/mandala depiction, and determining proper placement (sthāna) in a shrine or ritual layout.
