देवादिसृष्टिकथनम् (वसिष्ठशोकः, पराशरजन्म, एकलिङ्गपूजा, रुद्रदर्शनम्)
यदा तदा शक्तिसूनुर् अवतीर्णो महीतले शक्तिस्त्यक्त्वा तदा दुःखं पितॄणां समतां ययौ
yadā tadā śaktisūnur avatīrṇo mahītale śaktistyaktvā tadā duḥkhaṃ pitṝṇāṃ samatāṃ yayau
એ જ સમયે શક્તિનો પુત્ર પૃથ્વી પર અવતર્યો. અને શક્તિ દેહત્યાગ કરતાં પિતૃઓનું દુઃખ શમીને સમતામાં સ્થિર થયું।
Suta Goswami
It places sacred lineage and descent within the Purva-Bhaga’s creation narrative, showing how karmic disturbance (duḥkha) settles—supporting the Linga’s role as the stabilizing sign of Pati (Śiva) amid worldly change.
Indirectly: the movement from grief to samatā echoes Śiva-tattva as the ground of equilibrium beyond pāśa (bondage), toward which pashus (souls and ancestral beings) naturally return when causes of agitation cease.
No specific rite is stated; the key takeaway is the Shaiva yogic ideal of samatā (equanimity), a core disposition in Pāśupata-oriented practice that loosens pāśa and steadies the pashu toward Pati.
