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
聖なるデーヴァデーヴァは語った。「おお婆羅門よ、苦行の宝よ——かつて梵天はタパス(苦行)によって我を礼拝した。さらに我が降臨の目的のため、牟尼たちと神々の最勝者らもまた、その苦行によって我を歓喜させたのである。」
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.
