वासिष्ठकथनम् (आदित्य–सोमवंशवर्णनम् तथा रुद्रसहस्रनाम-प्रशंसा)
प्रतिष्ठा धर्मराजस्य सुद्युम्नस्य महात्मनः तत्पुरूरवसे प्रादाद् राज्यं प्राप्य महायशाः
pratiṣṭhā dharmarājasya sudyumnasya mahātmanaḥ tatpurūravase prādād rājyaṃ prāpya mahāyaśāḥ
Pratiṣṭhā, the illustrious daughter of the righteous king Sudyumna, having attained sovereignty, bestowed the kingdom upon Purūravas, thereby upholding the dharma of royal succession.
Suta Goswami (narrating royal genealogy to the sages of Naimisharanya)
It frames righteous kingship (rājadharma) as part of sustaining cosmic order; such order supports the conditions for Shiva-puja and dharma-based living through which the pashu (soul) gradually loosens pasha (bondage) and turns toward Pati (Shiva).
Indirectly: by emphasizing dharma-governed sovereignty, it reflects Shiva as Pati—the supreme regulator whose law (dharma) stabilizes society and enables beings to progress from bondage to grace-oriented alignment.
No specific rite is named; the takeaway is dharma as foundational discipline—ethical governance and rightful succession function as preparatory observance (niyama-like restraint) that supports Shaiva sadhana and steadiness in worship.
