Upamanyu’s Tapas, Shiva’s Indra-Form Test, and the Bestowal of Kshiroda and Gaṇapatya
भस्माधारान्महातेजा भस्ममुष्टिं प्रगृह्य च अथर्वास्त्रं ततस्तस्मै ससर्ज च ननाद च
bhasmādhārānmahātejā bhasmamuṣṭiṃ pragṛhya ca atharvāstraṃ tatastasmai sasarja ca nanāda ca
แล้วผู้มีเดชยิ่งใหญ่หยิบเถ้าศักดิ์สิทธิ์ (ภัสมะ) หนึ่งกำมือจากภาชนะภัสมะ จากนั้นก็ปล่อยอถรรวาสตราใส่เขา และเปล่งเสียงคำรามกึกก้อง
Suta Goswami (narrating the Purana, describing the internal action scene)
It elevates bhasma (vibhuti) from a mere ritual substance to a Shaiva emblem of consecration and protection—signifying that worship of the Linga is guarded and empowered by Shiva’s mantra-shakti and purity.
Shiva is shown as Mahātejas—radiant, sovereign, and decisive—using sacred ash and Atharva-mantra power to assert Pati’s mastery over forces that generate fear and bondage for the pashu.
The verse points to the Shaiva use of bhasma (vibhuti-dharana) as a purificatory and protective practice, and to mantra-empowerment (Atharva tradition) as a disciplined application of spiritual force aligned with Pashupata intent.
