Matsya Purana — Manvantaras
भृगुर्मरीचिरत्रिश्च अङ्गिराः पुलहः क्रतुः मनुर्दक्षो वसिष्ठश्च पुलस्त्यश्चापि ते दश //
bhṛgurmarīciratriśca aṅgirāḥ pulahaḥ kratuḥ manurdakṣo vasiṣṭhaśca pulastyaścāpi te daśa //
Bhrigu, Marichi, Atri, Angiras, Pulaha, Kratu, Manu, Daksha, Vasiṣṭha, and Pulastya—these are the ten (primeval sages).
It supports the creation framework by naming foundational sages (prajāpati-rishis) through whom beings and lineages proliferate after cosmic creation; it does not directly describe Pralaya here.
By foregrounding Manu and the great rishis as archetypal lawgivers and exemplars, the verse implicitly points rulers and householders toward dharma grounded in rishi-tradition (śruti/smṛti lineage) rather than personal whim.
No explicit Vāstu or temple rule appears in this verse; its ritual relevance is indirect—these rishis are authoritative transmitters of mantra, yajña-practice, and lineage-based rites referenced across Purāṇic ritual sections.
