रुणको भविता तस्य सुरथस्तत्सुतः स्मृतः । सुमित्रस्तत्सुतो भावी वंशनिष्ठांत एव हि

It highlights the Purāṇic view that worldly dynasties are finite; even honored lineages conclude, directing the listener toward lasting refuge in Pati (Lord Shiva) rather than in temporal power.
By emphasizing the end of a lineage, the text implicitly contrasts perishable worldly continuity with the eternal presence of Saguna Shiva worshiped as the Liṅga, whose grace alone grants enduring auspiciousness and liberation.
A practical takeaway is remembrance of Shiva through japa of the Pañcākṣarī (“Om Namaḥ Śivāya”) to transcend attachment to family-line pride and anchor the mind in Shiva as the eternal refuge.
