Upamanyu’s Tapas, Shiva’s Indra-Form Test, and the Bestowal of Kshiroda and Gaṇapatya
एवमुक्त्वा तु तं देवम् उपमन्युरभीतवत् शक्रं चक्रे मतिं हन्तुम् अथर्वास्त्रेण मन्त्रवित्
evamuktvā tu taṃ devam upamanyurabhītavat śakraṃ cakre matiṃ hantum atharvāstreṇa mantravit
ครั้นกล่าวดังนั้นแก่เทพองค์นั้นแล้ว อุปมันยุผู้ไม่หวาดหวั่นและชำนาญมนตร์ ก็ตั้งใจทำลายเจตนาของศักระด้วยอถรรวาสตรา
Suta Goswami (narrating the Purana to the sages; internal episode about Upamanyu and Indra)
It highlights that steadfast devotion to Pati (Shiva) grants spiritual fearlessness and mantra-siddhi, enabling a devotee like Upamanyu to counter even Indra’s hostile intent—implying that Shiva-bhakti and disciplined practice protect the worshipper beyond worldly authority.
Though Shiva is not named directly, the narrative frames a Shaiva devotee’s inner sovereignty: the Pashu (individual soul) aligned to Pati becomes unshaken and potent, indicating that Shiva-tattva empowers clarity, restraint, and the capacity to dissolve obstructive forces (pāśa) manifesting as pride or aggression.
Mantra-vidyā rooted in Atharvan tradition (atharvāstra) is emphasized—suggesting disciplined japa, mantra-siddhi, and the Pāśupata orientation where yogic steadiness and devotion transform mantra into effective spiritual force.
