Matsya Purana — Solar–Lunar Motions
देवादेवैर् अतीतास्तु रूपैर्नामभिरेव च तस्माद्वै साम्प्रतैर्देवैर् वक्ष्यामि वसुधातलम् //
devādevair atītāstu rūpairnāmabhireva ca tasmādvai sāmpratairdevair vakṣyāmi vasudhātalam //
The gods of former times have passed away—along with their forms and even their names. Therefore, I shall now describe the surface of the earth in relation to the gods of the present age.
It implies cyclical time: divine orders change across epochs, so earlier gods (their names and forms) pass away and a present set becomes relevant—an idea closely tied to recurring cosmic dissolutions and renewals.
By stressing the ‘present order’ of gods, it hints that dharma and ritual observances should be aligned with the currently prevailing cosmic administration—kings and householders uphold social and ritual order according to the living tradition of their time.
Indirectly, it signals that ritual frameworks (deity-names, forms, and invocations) can be time-specific; in temple worship and iconography, one should follow the currently authoritative deity-forms and liturgical conventions when mapping sacred space onto the earth.
