वासिष्ठकथनम् (आदित्य–सोमवंशवर्णनम् तथा रुद्रसहस्रनाम-प्रशंसा)
बन्धनस्तु सुरेन्द्राणां युधि शत्रुविनाशनः सखा प्रवासो दुर्वापः सर्वसाधुनिषेवितः
bandhanastu surendrāṇāṃ yudhi śatruvināśanaḥ sakhā pravāso durvāpaḥ sarvasādhuniṣevitaḥ
Él es el Vínculo (y también el que vincula) de los señores de los dioses; en la batalla es el destructor de los enemigos. Es el Amigo, el que mora en el retiro sagrado, el Señor difícil de alcanzar, y Aquel a quien todos los santos veneran y al que acuden.
Suta Goswami (narrating a Shiva-Sahasranama portion to the sages of Naimisharanya)
It frames Shiva as both the transcendent goal (durvāpaḥ) and the intimate refuge (sakhā), teaching that Linga-upāsanā is simultaneously devotion and liberation—approaching Pati who alone can cut the pasha of bondage.
Shiva-tattva is shown as paradoxically immanent and transcendent: He governs even the Devas (bandhanaḥ surendrāṇām), protects dharma by destroying hostile forces (śatru-vināśanaḥ), and yet remains beyond ordinary reach (durvāpaḥ), known through the sādhus’ realization.
The verse points to sādhus’ continual resort to Shiva (sarva-sādhu-niṣevitaḥ), implying disciplined upāsanā—japa/stotra of the Sahasranāma and Pāśupata-style vairāgya (pravāsaḥ as holy withdrawal) to approach the Hard-to-attain Lord.
