Matsya Purana — Marks of Karma-yoga and the Five Great Daily Sacrifices
ब्रह्मा विष्णुश्च भगवान् मार्तण्डो वृषवाहनः अष्टौ च वसवस्तद्वद् एकादश गणाधिपाः लोकपालाधिपाश्चैव पितरो मातरस्तथा //
brahmā viṣṇuśca bhagavān mārtaṇḍo vṛṣavāhanaḥ aṣṭau ca vasavastadvad ekādaśa gaṇādhipāḥ lokapālādhipāścaiva pitaro mātarastathā //
Brahmā, and Viṣṇu the Blessed Lord; Mārtaṇḍa (the Sun), and the Bull-borne one (Śiva); likewise the eight Vasus, the eleven chiefs of the Gaṇas, the presiding lords of the guardians of the quarters, and also the Pitṛs (ancestral fathers) and the Mothers (Mātṛkās)—all are to be understood as the divine hosts.
It does not describe pralaya directly; it catalogs key divine groups (devas, gaṇas, lokapālas, pitṛs, mātṛs) that structure the Purāṇic cosmos across cycles of creation and dissolution.
By naming lokapālas and pitṛs, it aligns with household and royal duties of maintaining order through worship—directional guardians in protective rites and Pitṛ offerings (śrāddha) as a core dharma obligation.
Ritually, it supports mandala-based worship where directions are presided over by lokapālas and protective gaṇas; such enumerations inform temple/altar consecrations and directional placements in Purāṇic-Āgamic practice.
