Matsya Purana — Soma
ततः पीतसुधं सोमं सूर्यो ऽसावेकरश्मिना आप्यायते सुषुम्नेन सोमं तु सोमपायिनम् //
tataḥ pītasudhaṃ somaṃ sūryo 'sāvekaraśminā āpyāyate suṣumnena somaṃ tu somapāyinam //
Thereupon, the Sun—by a single ray—nourishes and replenishes the Moon, who has drunk the nectar; and by way of Suṣumnā he sustains Soma, the drinker of Soma.
It does not describe pralaya directly; it explains an ongoing cosmic maintenance process—how the Sun replenishes Soma/Moon—supporting the Purana’s broader view of orderly cosmic functioning between dissolutions.
By analogy: as the Sun steadily nourishes Soma, a king/householder should sustain dependents through disciplined, regular support—upholding order (dharma) through consistent provision rather than erratic force.
Ritually, it reinforces Soma’s centrality in sacrificial imagination (Soma as nectar and as a cosmic principle); architecturally it is indirect, but such cosmology often underlies temple orientation to Sun–Moon cycles and calendrical ritual timing.
