Adhyaya 72 — Puradāha: Rudra’s Cosmic Chariot, Pāśupata-Vrata, and Brahmā’s Shiva-Stuti
शिव बुर्न्स् त्रिपुर अथ सज्यं धनुः कृत्वा शर्वः संधाय तं शरम् युक्त्वा पाशुपतास्त्रेण त्रिपुरं समचिन्तयत्
Śiva burns Tripura atha sajyaṃ dhanuḥ kṛtvā śarvaḥ saṃdhāya taṃ śaram yuktvā pāśupatāstreṇa tripuraṃ samacintayat
Then Śarva (Śiva), having strung his bow and set the arrow in place, empowered it with the Pāśupata weapon and fixed his divine resolve upon Tripura—so that the triple city would be reduced to ashes by Pati, the Lord who severs the pāśa (bond) of the bound paśu (souls).
Suta Goswami
It portrays Śiva as the supreme Pati whose focused will and divine power dissolve impurity and bondage; in Linga-worship this is contemplated as the Lord’s grace that burns the inner “Tripura” of ego, karma, and māyā.
Śiva is shown as sovereign and self-sufficient: by mere concentration and the Pāśupata power, he accomplishes cosmic dissolution—signifying the Lord’s icchā-śakti and his role as remover of pāśa for the paśu.
The key practice is dhyāna/ekāgratā (one-pointed contemplation): Śiva “fixes his intent” on Tripura, reflecting the Pāśupata emphasis on focused meditation empowered by mantra and divine śakti.
