वासिष्ठकथनम् (आदित्य–सोमवंशवर्णनम् तथा रुद्रसहस्रनाम-प्रशंसा)
वीणी च पणवी ताली नाली कलिकटुस् तथा सर्वतूर्यनिनादी च सर्वव्याप्यपरिग्रहः
vīṇī ca paṇavī tālī nālī kalikaṭus tathā sarvatūryaninādī ca sarvavyāpyaparigrahaḥ
അവൻ വീണയും പണവിയും, താളവും നാളിയും; കൂടാതെ കലികടു—തീക്ഷ്ണമായി കുത്തുന്ന നാദവും. അവൻ എല്ലാ തൂര്യവാദ്യങ്ങളുടെയും നിനാദം; സർവ്വവ്യാപിയായ പ്രഭു, എല്ലാം തന്റെ ഉള്ളിൽ ഉൾക്കൊള്ളുന്നവൻ.
Suta Goswami (narrating Shiva’s attributes to the sages of Naimisharanya)
It frames Shiva as sarva-vyāpī (all-pervading) and present even as sacred sound; thus Linga-pūjā is not limited to form alone—sound, mantra, and ritual resonance are also direct approaches to Pati.
Shiva-tattva is presented as the inner essence of nāda (cosmic vibration) and as the one who contains all phenomena—Pati who pervades and gathers the universe, while remaining its sovereign ground.
Nāda-oriented upāsanā: using mantra, rhythmic recitation, and attentive absorption in sound as aids in Pashupata-aligned meditation, turning sensory vibration into remembrance of Shiva.
