अध्याय 66: इक्ष्वाकुवंश-ऐलवंशप्रवाहः (त्रिशङ्कु-राम-ययात्यादि-प्रकरणम्)
सर्वे पाशुपते ज्ञानम् अधीत्य परमेश्वरम् समभ्यर्च्य यथाज्ञानम् इष्ट्वा यज्ञैर्यथाविधि
sarve pāśupate jñānam adhītya parameśvaram samabhyarcya yathājñānam iṣṭvā yajñairyathāvidhi
Having all studied the Pāśupata wisdom, they worshipped Parameśvara (Śiva) in accordance with their understanding; and, following the prescribed rule, they duly performed sacrifices, offering them as acts oriented to Pati—the Lord who frees the paśu (souls) from the bonds of pāśa.
Suta Goswami (narrating the Purana to the sages of Naimisharanya)
It links Shiva worship to Pāśupata-jñāna: ritual (yajña/arcana) becomes effective when performed with correct Shaiva understanding and scriptural procedure, oriented to Parameśvara as Pati.
Shiva is named Parameśvara—the Supreme Lord—implying the Pati principle: the transcendent master who receives worship and is capable of releasing the paśu (individual soul) from pāśa (bondage).
Study of Pāśupata doctrine followed by disciplined worship (samabhyarcana) and yajña performed yathāvidhi—ritual correctness integrated with Shaiva insight, a hallmark of Pāśupata-oriented practice.
