वासिष्ठकथनम् (आदित्य–सोमवंशवर्णनम् तथा रुद्रसहस्रनाम-प्रशंसा)
अथर्वशीर्षः सामास्य ऋक्सहस्रोर्जितेक्षणः यजुः पादभुजो गुह्यः प्रकाशौजास्तथैव च
atharvaśīrṣaḥ sāmāsya ṛksahasrorjitekṣaṇaḥ yajuḥ pādabhujo guhyaḥ prakāśaujāstathaiva ca
അവന്റെ ശിരസ് അഥർവ്വവേദം; അവന്റെ മുഖം സാമവേദം; അവന്റെ ശക്തമായ ദൃഷ്ടി സഹസ്ര ഋക്കുകൾ; അവന്റെ പാദങ്ങൾ യജുസ്—അവൻ ഗുഹ്യൻ, അന്തർലീനനായ പ്രഭു; അതുപോലെ പ്രകാശമയ ഓജസ്സുള്ളവൻ।
Suta Goswami (narrating Shiva’s epithets to the sages of Naimisharanya)
It establishes that the Linga is not merely a symbol but the very source and inner meaning of Vedic mantra—Atharva, Sāman, Ṛk, and Yajus—so Linga-puja is worship of the Veda-bodied Pati (Shiva) through mantra and offering.
Shiva is both guhya (transcendent, hidden from sense and mind) and prakāśaujās (self-revealing luminous power). In Shaiva Siddhanta terms, He is Pati—beyond pasha (bondage) and yet the revealer of knowledge that frees the pashu (soul).
Mantra-centered worship: recitation of Vedic hymns and their Shaiva import while meditating that all Vedas culminate in Shiva. Yogically, it points to inner mantra-japa where the seeker turns from outer sound to the hidden Lord (guhya) as inner light (prakāśa).
