दुर्वाससः तपः-प्रभावः तथा देवाः ब्रह्म-विष्ण्वोः शरणागमनम् | Durvāsā’s Tapas and the Devas’ Appeal to Brahmā and Viṣṇu

prāṇānāyamya vidhivannirvindhyātaṭinītaṭe | tapaścacāra sumahadadvandvo'bdaśatammuniḥ
Having regulated his life-breath through prāṇāyāma according to the prescribed discipline, the sage performed exceedingly great austerities on the bank of the river Nirvindhyā—free from the pairs of opposites—for a full hundred years.

Sthala Purana: Tapas on the Nirvindhyā riverbank: a classic purāṇic setup where sustained yogic discipline at a tīrtha draws divine response.
Significance: Tīrtha + prāṇāyāma + advaṃdva-tapas is portrayed as a purifier of pāśa (mala/karma), making the aspirant fit for īśvara-anugraha.
Role: teaching
It teaches that steadfast tapas supported by disciplined prāṇāyāma and an advandva mind (equanimity beyond opposites) purifies the bound soul (paśu) and makes it fit to receive Shiva’s grace, the true cause of liberation in Shaiva Siddhanta.
Such sustained austerity and breath-discipline are presented as inner worship that prepares the devotee for Saguna Shiva-upāsanā—steady contemplation, mantra-japa, and reverent service to the Linga—so devotion becomes unwavering rather than mood-dependent.
The verse directly points to prāṇāyāma done विधिवत् (as per rule) and tapas with equanimity; in Shiva Purana practice this is typically paired with Shiva-mantra japa (especially the Panchakshara), along with purity disciplines like bhasma (tripuṇḍra) and rudrākṣa where appropriate.
