Matsya Purana — Lineage of the Pitṛs
एतदुद्देशतः प्रोक्तं नामाष्टशतमुत्तमम् अष्टोत्तरं च तीर्थानां शतमेतदुदाहृतम् //
etaduddeśataḥ proktaṃ nāmāṣṭaśatamuttamam aṣṭottaraṃ ca tīrthānāṃ śatametadudāhṛtam //
Thus, in brief, the supreme set of one hundred and eight names has been declared; and likewise this set of one hundred and eight sacred pilgrimage-sites (tīrthas) has been recited.
This verse does not describe Pralaya; it functions as a concluding summary that a set of 108 sacred names and 108 tīrthas has been listed.
It supports dharmic life by directing kings and householders toward tīrtha-yātrā and remembrance of sacred names—standard Purāṇic means for merit, purification, and public religious order.
The ritual takeaway is the canonical emphasis on 108 (a sacred count) for recitation and tīrtha enumeration; no specific Vāstu or temple-construction rule is stated in this verse.
