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, a ilustre filha de Sudyumna, o rei justo e magnânimo, tendo alcançado a soberania, concedeu o reino a Purūravas, preservando assim o dharma da sucessão real.
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.
