वासिष्ठकथनम् (आदित्य–सोमवंशवर्णनम् तथा रुद्रसहस्रनाम-प्रशंसा)
तुम्बवीणो महाकोप ऊर्ध्वरेता जलेशयः उग्रो वंशकरो वंशो वंशवादी ह्यनिन्दितः
tumbavīṇo mahākopa ūrdhvaretā jaleśayaḥ ugro vaṃśakaro vaṃśo vaṃśavādī hyaninditaḥ
He is the player of the tuṃbā-vīṇā; the Great Wrath that destroys impurity; the Ūrdhvareta, whose vital seed flows upward, established in brahmacarya; the Lord who lies within the waters; the Fierce One; the maker of lineages; the lineage itself; the revealer of the sacred lineage through teaching and recitation; and the Blameless (Anindita), the stainless Pati beyond all fault.
Suta Goswami (narrating Shiva’s Sahasranama to the sages of Naimisharanya)
These names frame Shiva as the stainless Pati who supports creation (jaleśaya) and purifies devotees through yogic power (ūrdhvaretā) and fierce grace (mahākopa), guiding Linga-upāsanā toward inner purification and liberation from pasha.
Shiva-tattva is shown as both cosmic (abiding in the primal waters, source and continuity of lineages) and transcendent (anindita—faultless), whose fierce aspect destroys bondage while remaining the pure Lord of all pashus.
The epithet ūrdhvaretā points to brahmacarya and sublimation of vital energy central to Pāśupata-oriented sādhanā, supporting steadiness in japa, dhyāna, and disciplined Linga-pūjā.
