वंशानुवर्णनम् — सात्वतवंशः, स्यमन्तक-प्रसङ्गः, कृष्णावतारः, शिवप्रसादः (पाशुपतयोगः)
तस्मादप्यभिजित्पुत्र उत्पन्नो ऽस्य पुनर्वसुः अश्वमेधं स पुत्रार्थम् आजहार नरोत्तमः

From him too was born Punarvasu, the son of Abhijit. That best among men performed the Aśvamedha sacrifice to obtain a son, seeking progeny under the higher order that ultimately rests in Pati, Lord Śiva.
Suta Goswami (narrating to the sages at Naimisharanya)
It frames Vedic yajña (Aśvamedha) as a dharmic means for worldly aims like progeny, which in Shaiva understanding bears fruit through Śiva’s anugraha (grace), the ultimate ground of all results.
Though Śiva is not named in the shloka, the Purāṇic Shaiva lens treats all karmic fruits as dependent on Pati (Śiva) as the inner ruler; the Pashu’s desire for a son is fulfilled only when aligned with that higher order.
A royal Vedic rite—Aśvamedha—performed with the specific intention (saṅkalpa) of progeny; it implicitly contrasts external ritual (karma) with the Shaiva ideal of seeking Śiva’s grace that loosens pāśa (bondage).
