Matsya Purana — Narasimha’s Victory over Hiraṇyakaśipu and the Catalogue of Apocalyptic Omens
वामे तु दक्षिणे चैव स्थितौ शुक्रबृहस्पती शनैश्चरो लोहिताङ्गो ज्वलनाङ्गसमद्युतिः //
vāme tu dakṣiṇe caiva sthitau śukrabṛhaspatī śanaiścaro lohitāṅgo jvalanāṅgasamadyutiḥ //
On the left and on the right stand Venus and Bṛhaspati (Jupiter); and Śanaiścara (Saturn) is reddish-limbed, shining with a fiery-bodied brilliance.
This verse does not describe Pralaya directly; it belongs to an astral/omen context, detailing the placement and appearance of planets as part of cosmic order and interpretive signs.
By noting planetary placements and qualities, it supports the Purāṇic ideal that kings and householders align major actions (state decisions, rites, journeys) with auspicious timing and heed celestial indicators used in traditional counsel.
While no building rule is stated, such graha-sthiti verses commonly inform ritual calendrics (muhūrta) used for temple consecrations, image installations, and other rites—choosing times when planetary indications are favorable.
