Matsya Purana — Glory of Tīrtha-Śrāddha: Best Times
शुक्रतीर्थं च विख्यातं तीर्थं सोमेश्वरं परम् सर्वव्याधिहरं पुण्यं शतकोटिफलाधिकम् //
śukratīrthaṃ ca vikhyātaṃ tīrthaṃ someśvaraṃ param sarvavyādhiharaṃ puṇyaṃ śatakoṭiphalādhikam //
And the renowned Śukra-tīrtha—this supreme holy ford of Someśvara—is meritorious, removes all diseases, and yields a reward exceeding that of a hundred koṭis (śata-koṭi) of ordinary pious acts.
This verse does not address pralaya; it focuses on tīrtha-māhātmya—declaring the extraordinary merit and healing power of Śukra-tīrtha at Someśvara.
It supports the Purāṇic ethic that rulers and householders should uphold dharma through tīrtha-yātrā, dāna, and ritual purity—here, pilgrimage to Someśvara is praised as a highly meritorious act that promotes welfare (health and पुण्य).
Ritually, it implies the sanctity of worship/bathing at a Śaiva site (Someśvara) and frames the tīrtha as a locus of healing and merit; no explicit Vāstu or temple-construction rule is stated in this verse.
