Matsya Purana — The Array of the Gods: Description of the Vaiṣṇava Host and the Lokapālas
सूर्यः सप्ताश्वयुक्तेन रथेनामितगामिना श्रिया जाज्वल्यमानेन दीप्यमानैश्च रश्मिभिः //
sūryaḥ saptāśvayuktena rathenāmitagāminā śriyā jājvalyamānena dīpyamānaiśca raśmibhiḥ //
The Sun, mounted on a chariot yoked with seven horses—moving with immeasurable speed—blazes with splendor, and shines forth with radiant rays.
It does not directly describe Pralaya; it highlights Sūrya’s cosmic function through imagery of speed, brilliance, and rays—features that support the ordered movement of time and the world.
By praising Sūrya as radiant and world-sustaining, the verse supports the Purāṇic ethic of daily reverence to the Sun (sandhyā, discipline, regularity), virtues expected of householders and rulers who must uphold order (dharma) like the Sun’s steady course.
The seven-horsed solar chariot is a standard iconographic motif for Sūrya images; ritually, such verses function as Sūrya-stuti for recitation, and architecturally they align with temple/altar orientation and emphasis on light (east-facing sanctums) in Vastu-informed practice.
