Matsya Purana — The Attendant Hosts of the Sun and Moon: Monthly Gaṇas
त्रयस्त्रिंशत्सहस्राणि देवाः सोमं पिबन्ति वै इत्येवं पीयमानस्य कृष्णे वर्धन्ति ताः कलाः //
trayastriṃśatsahasrāṇi devāḥ somaṃ pibanti vai ityevaṃ pīyamānasya kṛṣṇe vardhanti tāḥ kalāḥ //
The gods—thirty-three thousand in number—indeed drink Soma. Thus, as it is drunk in this manner, in the dark fortnight (kṛṣṇa-pakṣa) those lunar portions (kalās) increase.
It does not describe Pralaya directly; it explains a cosmological mechanism—how Soma and the Moon’s kalās are affected by divine consumption—used in Purāṇic accounts of time, cycles, and celestial order.
Indirectly, it supports dharma through calendrical order: understanding pakṣas (fortnights) underpins correct timing for rites, vows, śrāddha, and royal/public ceremonies that a king and householder are expected to maintain.
Ritually, it points to Soma as sacred nectar and to pakṣa-based timing; many offerings and observances are scheduled by kṛṣṇa-pakṣa/śukla-pakṣa. No direct Vāstu or temple-construction rule is stated in this verse.
