Matsya Purana — Cosmic Architecture of Sun–Moon and the ‘Houses of the Gods’
वर्तन्ते वर्तमानैश्च सुरैः सार्धं तु स्थानिनः सूर्यो देवो विवस्वांश्च अष्टमस्त्वदितेः सुतः //
vartante vartamānaiśca suraiḥ sārdhaṃ tu sthāninaḥ sūryo devo vivasvāṃśca aṣṭamastvaditeḥ sutaḥ //
Along with the presently reigning gods, the presiding deities who hold their appointed stations also continue their functions. Among them is the Sun-god Vivasvān—Aditi’s eighth son.
It emphasizes continuity of cosmic administration: even as eras change, presiding offices (sthānin deities) and the currently reigning gods continue their roles—an idea often used in Purāṇic cosmology to explain order across cycles.
By highlighting “stationed” roles and orderly succession, it implicitly supports dharma as stable governance—kings and householders should likewise uphold their appointed duties in coordination with the wider social and cosmic order.
Direct Vāstu or temple-rule content is not stated here; ritually, it underlines Sūrya (Vivasvān) as a key deity within the cosmic hierarchy, supporting Sūrya-related worship and calendrical observances tied to solar order.
