Indra’s Account: Shilada’s Tapas and Shiva’s Manifestation as Nandi
श्रीदेवदेव उवाच पूर्वमाराधितो विप्र ब्रह्मणाहं तपोधन तपसा चावतारार्थं मुनिभिश् च सुरोत्तमैः
śrīdevadeva uvāca pūrvamārādhito vipra brahmaṇāhaṃ tapodhana tapasā cāvatārārthaṃ munibhiś ca surottamaiḥ
శ్రీ దేవదేవుడు పలికెను—హే విప్రా, హే తపోధనా! పూర్వం బ్రహ్మ తపస్సుతో నన్ను ఆరాధించాడు; నా అవతారార్థమున మునులు మరియు దేవోత్తములు కూడా తపస్సుతో నన్ను ప్రసన్నం చేశారు।
Shiva (Devadeva)
It frames Śiva as the Pati who is approached through ārādhana and tapas; Linga-worship is thus grounded in disciplined propitiation that invites His manifest presence (prādurbhāva/avatāra) for the world’s welfare.
Śiva-tattva is shown as sovereign and responsive: though transcendent, Devadeva is pleased by tapas performed by Brahmā, sages, and devas, and He manifests (descends) by grace when invoked for a cosmic purpose.
Tapas as a Pāśupata-oriented discipline—focused austerity and propitiation (ārādhana) directed to Pati (Śiva) to loosen pāśa (bondage) and catalyze divine intervention/manifestation.
