Adhyaya 70: आदिसर्गः—महत्-अहङ्कार-तन्मात्रा-भूतसृष्टिः, ब्रह्माण्डावरणम्, प्रजासर्गः, त्रिमूर्ति-शैवाधिष्ठानम्
तस्मात् सनत्कुमारेति नामास्येह प्रकीर्तितम् सनन्दं सनकं चैव विद्वांसं च सनातनम्
tasmāt sanatkumāreti nāmāsyeha prakīrtitam sanandaṃ sanakaṃ caiva vidvāṃsaṃ ca sanātanam
Therefore, in this account he is celebrated by the name “Sanatkumāra”; and (along with him) Sananda, Sanaka, and the wise Sanātana are also proclaimed—those eternally youthful sages renowned for steadfast knowledge of the Pati (Śiva) and the release of the paśu from pāśa.
Suta Goswami (narrating the Linga Purana to the sages of Naimisharanya)
It anchors Linga Purana authority in the lineage of the eternally youthful Kumaras—renunciant sages associated with pure jñāna—implying that true Linga devotion is grounded in right knowledge of Śiva as Pati, not merely external rite.
By invoking the Kumaras as “wise” and “eternal,” it points to Shiva-tattva as the timeless Pati known through jñāna: the Lord who enables the paśu (bound soul) to transcend pāśa (bondage) and realize freedom.
The verse primarily highlights jñāna-oriented renunciation associated with the Kumara tradition—supportive of Pāśupata discipline—where inner purity, discernment, and devotion to Śiva undergird any Linga-pūjā.
