Upamanyu’s Tapas, Shiva’s Indra-Form Test, and the Bestowal of Kshiroda and Gaṇapatya
अथ जगाम मुनेस्तु तपोवनं गजवरेण सितेन सदाशिवः सह सुरासुरसिद्धमहोरगैर् अमरराजतनुं स्वयमास्थितः
atha jagāma munestu tapovanaṃ gajavareṇa sitena sadāśivaḥ saha surāsurasiddhamahoragair amararājatanuṃ svayamāsthitaḥ
Then Sadāśiva went to the sage’s forest-hermitage of austerity, mounted upon a splendid white elephant, and accompanied by Devas, Asuras, Siddhas, and great serpents—Himself assuming the majestic form and splendor of the Lord of the immortals.

It frames Shiva as the sovereign Pati who freely comes to the tapasvin’s sacred space—implying that Linga-upāsanā and tapas culminate in the Lord’s direct anugraha (grace), not merely ritual merit.
Shiva is shown as Sadāśiva, independent and self-assuming forms (svayam āsthitaḥ), transcending all classes of beings while being accompanied by them—signaling His supremacy over Deva, Asura, Siddha, and Nāga as their inner Lord (Pati).
Tapas in the tapovana is foregrounded: sustained austerity and contemplative discipline aligned with Pashupata orientation, where the bound soul (paśu) ripens for Shiva’s grace that loosens pāśa (bondage).
