Matsya Purana — Pitṛ Worlds
एकाष्टकाभवत् पश्चाद् ब्रह्मलोके गता सती त्रय एते गणाः प्रोक्ताश् चतुर्थं तु वदाम्यतः //
ekāṣṭakābhavat paścād brahmaloke gatā satī traya ete gaṇāḥ proktāś caturthaṃ tu vadāmyataḥ //
Afterwards, she became Ekāṣṭakā and, as the virtuous one, went to Brahmā’s world (Brahmaloka). These three groups (gaṇas) have been declared; now I shall speak of the fourth.
It reflects post-creation cosmic ordering: beings are classified into distinct gaṇas and assigned realms like Brahmaloka, emphasizing structured cosmology rather than a direct Pralaya event.
Indirectly, it models dharmic order: just as cosmic beings have defined classes and destinations, kings and householders are expected to follow their varṇa–āśrama duties with steadiness (satī-like fidelity to dharma).
No explicit Vāstu or ritual procedure is stated; the key takeaway is hierarchical realm-concept (Brahmaloka), which later Purāṇic ritual and temple traditions sometimes map to graded sacred spaces and cosmological symbolism.
