Upamanyu’s Tapas, Shiva’s Indra-Form Test, and the Bestowal of Kshiroda and Gaṇapatya
क्षीरार्थमदहत्सर्वं तपसा तं निवारय एतस्मिन्नन्तरे देवः पिनाकी परमेश्वरः शक्ररूपं समास्थाय गन्तुं चक्रे मतिं तदा
kṣīrārthamadahatsarvaṃ tapasā taṃ nivāraya etasminnantare devaḥ pinākī parameśvaraḥ śakrarūpaṃ samāsthāya gantuṃ cakre matiṃ tadā
为求牛乳,他以苦行之火焚尽一切;当以苦行之力制止他。其间,主宰——执持弓者毗那迦的至上自在天——化作释迦(因陀罗)之形,遂起意出行。
Suta Goswami (narrating to the sages at Naimisharanya)
It highlights Shiva as Pati who intervenes to protect cosmic order; Linga worship centers on this Parameshvara who governs and pacifies destructive imbalance through grace and purposeful action.
Shiva-tattva is shown as sovereign freedom (svātantrya): Parameshvara can assume any form (here, Śakra) to guide events, revealing the Lord’s mastery over roles and powers without being bound by them.
Tapas (austerity) is presented as the restraining spiritual force—aligned with Pāśupata discipline—by which destructive tendencies are checked and brought under dharmic control.
