वासिष्ठकथनम् (आदित्य–सोमवंशवर्णनम् तथा रुद्रसहस्रनाम-प्रशंसा)
रत्नभूतो ऽथ रत्नाङ्गो महार्णवनिपातवित् मूलं विशालो ह्यमृतं व्यक्ताव्यक्तस्तपोनिधिः
ratnabhūto 'tha ratnāṅgo mahārṇavanipātavit mūlaṃ viśālo hyamṛtaṃ vyaktāvyaktastaponidhiḥ
祂是宝珠之精髓,其肢体如宝石般辉耀;知晓沉入大宇宙海之奥秘者。祂是根本因,是广大者;祂即甘露(Amṛta),不死之精华。祂既显现亦不显现;为苦行功德(tapas)之宝藏——此即彼至上之帕提,主宰湿婆。
Suta Goswami (narrating the Shiva Sahasranama within the Linga Purana to the sages of Naimisharanya)
It frames the Linga as the mūla (root-cause) and amṛta (immortality) itself—guiding the devotee to worship not merely a symbol, but Pati (Śiva) who pervades both the visible and invisible.
Śiva is presented as vyakta-avyakta—simultaneously manifest in form and unmanifest beyond form—while remaining viśāla (all-pervading), the deathless ground of all beings (Pashus) and their liberation from Pāśa (bondage).
The epithet taponidhiḥ emphasizes tapas and disciplined Pāśupata-oriented sādhanā: sustained austerity, mantra-japa, and contemplative absorption on the Linga as the vast, deathless Reality.
