नन्दिकेश्वरोत्पत्तिः — Nandikesvara’s Origin, Shiva’s Boons, and the Rise of Sacred Rivers
शालङ्कायनपुत्रो वै शिलादः पुत्रवत्सलः उपदिष्टा हि तेनैव ऋक्शाखा यजुषस् तथा
śālaṅkāyanaputro vai śilādaḥ putravatsalaḥ upadiṣṭā hi tenaiva ṛkśākhā yajuṣas tathā
Indeed, Śilāda—son of Śālaṅkāyana and deeply affectionate toward his son—was the very one who taught the branch of the Ṛgveda, and likewise the branch of the Yajurveda.
Suta Goswami (narrating the Purana to the sages of Naimisharanya)
It grounds Shaiva practice in Vedic authority by showing how recognized Ṛg and Yajur recensions were preserved through rishi lineages—supporting the legitimacy of Vedic mantras used in Mahadeva’s worship.
Indirectly: by highlighting faithful Vedic transmission, it points to Shiva as Pati—the Lord approached through śruti-backed mantra and disciplined lineage, which stabilizes the pashu’s (soul’s) path away from pāśa (bondage).
Śākhā-paramparā (lineage-based preservation of Vedic recensions), which underpins proper mantra-vidhi for Shiva-pūjā; no specific Pāśupata yoga technique is explicitly stated in this verse.
