Matsya Purana — Cosmic Architecture of Sun–Moon and the ‘Houses of the Gods’
द्युतिमान्धर्मयुक्तश्च सोमो देवो वसुः स्मृतः शुक्रो दैत्यस्तु विज्ञेयो भार्गवो ऽसुरयाजकः //
dyutimāndharmayuktaśca somo devo vasuḥ smṛtaḥ śukro daityastu vijñeyo bhārgavo 'surayājakaḥ //
Soma (the Moon) is remembered as radiant and devoted to dharma—a deva, a Vasu. But Śukra (Venus) is to be understood as a Daitya: Bhārgava, descended from Bhṛgu, the priest who performs sacrifices for the Asuras.
This verse does not describe pralaya; it classifies planetary deities by lineage and function—Soma as a deva/Vasu aligned with dharma, and Śukra as Bhārgava, the sacrificial priest of the Asuras.
Indirectly, it supports the Purāṇic-Jyotiṣa worldview used by kings and householders for calendrical and ritual decisions: knowing the grahas’ identities (deva/daitya affiliations) frames auspicious timing, ritual propriety, and ethical orientation toward dharma.
The ritual point is explicit: Śukra is called 'asurayājaka'—the one who officiates sacrifices for Asuras—marking him as a paradigmatic priestly figure (ācārya) in Purāṇic lore, though no specific Vāstu or temple-building rule is stated in this verse.
