वासिष्ठकथनम् (आदित्य–सोमवंशवर्णनम् तथा रुद्रसहस्रनाम-प्रशंसा)
अथर्वशीर्षः सामास्य ऋक्सहस्रोर्जितेक्षणः यजुः पादभुजो गुह्यः प्रकाशौजास्तथैव च
atharvaśīrṣaḥ sāmāsya ṛksahasrorjitekṣaṇaḥ yajuḥ pādabhujo guhyaḥ prakāśaujāstathaiva ca
Dia yang kepalanya ialah Atharva (Veda), wajahnya ialah Sāman; pandangan-Nya yang perkasa ialah seribu Ṛk; kaki-Nya ialah Yajus—Dialah Yang Tersembunyi, dan juga Yang bercahaya dengan kuasa sinar yang gemilang.
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).
