Matsya Purana — Soma
स्थानेषु पात्यमाना ये यातनास्थेषु तेषु वै शाल्मल्यां वैतरण्यां च कुम्भीपाकेद्धवालुके //
sthāneṣu pātyamānā ye yātanāstheṣu teṣu vai śālmalyāṃ vaitaraṇyāṃ ca kumbhīpākeddhavāluke //
Those who are cast down into such places of torment are made to suffer there indeed—among hells such as Śālmalyā, Vaitaraṇī, Kumbhīpāka, and the burning sands.
This verse is not about Pralaya; it describes post-death karmic consequences—souls being cast into specific hell-realms (narakas) for torment.
By listing narakas like Vaitaraṇī and Kumbhīpāka, the text reinforces dharma: rulers and householders must uphold ethical conduct and restrain harmful actions, since wrongdoing leads to severe afterlife punishments.
No Vāstu or temple-architecture rule appears here; the ritual takeaway is moral-ritual causality—right conduct (and expiatory practices elsewhere in the Purana) is urged to avoid naraka destinies.
