अन्धकानुग्रहः—शूलारोपणं, रुद्रस्मरण-फलम्, तथा गाणपत्य-प्रदानम् (अध्याय 93)
पुरान्धक इति ख्यातस् तपसा लब्धविक्रमः प्रसादाद्ब्रह्मणः साक्षाद् अवध्यत्वमवाप्य च
purāndhaka iti khyātas tapasā labdhavikramaḥ prasādādbrahmaṇaḥ sākṣād avadhyatvamavāpya ca
அவன் ‘புராந்தகன்’ என்று புகழ்பெற்றான். தவத்தால் வீரத்தைக் கண்டான்; நேரே பிரம்மாவின் அருளால் கொல்லமுடியாத தன்மையின் வரத்தையும் பெற்றான்।
Suta Goswami
It contrasts worldly boons gained by tapas (power/invulnerability) with the higher Shaiva aim: surrender to Pati (Śiva) through Linga-centered devotion, which alone cuts pasha (bondage) rather than inflating ego.
Implicitly, it shows that even “invincibility” granted by Brahmā is conditional within saṃsāra; Śiva as Pati transcends such limits, and only His anugraha leads the pashu beyond the net of pasha.
Tapas (austerity) is highlighted as a yogic force for gaining siddhi-like power; the Shaiva takeaway is that tapas must be yoked to Pashupata orientation—humility and devotion to Śiva—otherwise it reinforces bondage.
