Adhyaya 75: Nishkala–Sakala Shiva, Twofold Linga, and the Supremacy of Dhyana-Yajna
सूत उवाच परमार्थविदः केचिद् ऊचुः प्रणवरूपिणम् विज्ञानमिति विप्रेन्द्राः श्रुत्वा श्रुतिशिरस्यजम्
sūta uvāca paramārthavidaḥ kecid ūcuḥ praṇavarūpiṇam vijñānamiti viprendrāḥ śrutvā śrutiśirasyajam
Sūta said: O best of Brahmins, some knowers of the highest truth declared, after hearing of Him who is born from the crest of the Veda, that the supreme liberating Knowledge is of the very form of the Praṇava (Oṁ)—the Pati (Lord) revealed as the essence of the Upaniṣadic summit.
Suta
It identifies the highest principle behind Linga-upāsanā as realized Knowledge (vijñāna) embodied in Praṇava (Oṁ), pointing the worshipper from external symbol to the Upaniṣadic essence of Śiva as Pati.
Śiva-tattva is presented as the Veda’s summit (śruti-śiras) and as Praṇava itself—supreme consciousness that grants liberating insight, the Lord (Pati) who is known through inner realization rather than mere concept.
Praṇava-upāsanā (Oṁ-japa with contemplative insight) is implied as a Pāśupata-oriented practice: the pashu (soul) loosens pāśa (bondage) through vijñāna by meditating on Śiva as the meaning and sound-form of Oṁ.
