Matsya Purana — Navagraha Sacrifice for Planetary Pacification and Prosperity
आदित्याभिमुखाः सर्वाः साधिप्रत्यधिदेवताः स्थापनीया मुनिश्रेष्ठ नोत्तरेण पराङ्मुखाः //
ādityābhimukhāḥ sarvāḥ sādhipratyadhidevatāḥ sthāpanīyā muniśreṣṭha nottareṇa parāṅmukhāḥ //
O best of sages, all deities—together with their attendant and presiding divinities—should be installed facing the Sun (east). They should not be placed toward the north while turned away, with their backs facing.
This verse does not discuss Pralaya; it gives a Vastu/ritual rule for installing deities, emphasizing auspicious eastward (Sun-facing) orientation.
It guides patrons (kings/householders) sponsoring temples or shrines to follow correct installation orientation, a key duty in maintaining dharma through proper worship and public religious works.
It prescribes that images and their associated subsidiary/presiding deities be installed facing east (toward the Sun) and warns against a northward placement that results in the deity being turned away—an inauspicious orientation in consecration practice.
