Matsya Purana — The Attendant Hosts of the Sun and Moon: Monthly Gaṇas
स्थानाभिमानिनां ह्येतत् स्थानं मन्वन्तरेषु वै अतीतानागतानां च वर्तन्ते साम्प्रतं च ये //
sthānābhimānināṃ hyetat sthānaṃ manvantareṣu vai atītānāgatānāṃ ca vartante sāmprataṃ ca ye //
Indeed, this is the appointed station of the presiding powers identified with their respective offices; it operates throughout the Manvantaras—of those that have passed, those yet to come, and those that are present now.
It emphasizes continuity of cosmic administration across time-cycles: even as Manvantaras pass (and dissolutions occur between them), the ‘stations’ or offices of presiding powers persist as an ordered system through past, present, and future cycles.
By analogy, it supports the Purāṇic ethic of role-based duty (adhikāra): just as cosmic offices function in an ordered succession, kings and householders should uphold their appointed responsibilities steadily across changing circumstances.
While not directly about Vāstu or ritual procedure, it supplies the underlying principle used in Vāstu-śāstra and ritual systems: stable ‘stations’ (sthāna) and presiding authorities—i.e., correct placement and assigned guardianship—are essential for order and efficacy.
