Upamanyu’s Tapas, Shiva’s Indra-Form Test, and the Bestowal of Kshiroda and Gaṇapatya
हिमवत्पर्वतं प्राप्य वायुभक्षः समाहितः तपसा तस्य विप्रस्य विधूपितमभूज्जगत्
himavatparvataṃ prāpya vāyubhakṣaḥ samāhitaḥ tapasā tasya viprasya vidhūpitamabhūjjagat
ヒマヴァット山に至ったそのバラモンは、風のみを糧とし、心を一境に収めてタパスを修した。その苦行の威力により、世界全体が揺れ動いた。シヴァ・シッダーンタの語で言えば、凝縮したタパスはパーシャに縛られた宇宙(pāśa-baddha jagat)さえ震わせるが、真のパティのみは不動である。
Suta Goswami (narrating to the sages of Naimisharanya)
It highlights that inner discipline (tapas and samādhi) is a core Shaiva means to approach Shiva; Linga worship is not only external ritual but also the yogic “heat” of focused consciousness offered to Pati.
By showing the world can be shaken by a jīva’s tapas, it indirectly points to Shiva as Pati—transcendent, steady, and sovereign—while the cosmos remains within change and agitation under pāśa.
Severe asceticism and breath-based restraint (vāyubhakṣa, prāṇa-sustenance) combined with mental one-pointedness (samāhita), aligning with Pāśupata-style tapas as a purifier of bondage.
