देवादिसृष्टिकथनम् (वसिष्ठशोकः, पराशरजन्म, एकलिङ्गपूजा, रुद्रदर्शनम्)
सम्पूज्य शिवसूक्तेन त्र्यंबकेन शुभेन च जप्त्वा त्वरितरुद्रं च शिवसंकल्पमेव च
sampūjya śivasūktena tryaṃbakena śubhena ca japtvā tvaritarudraṃ ca śivasaṃkalpameva ca
Après avoir rendu le culte comme il se doit avec le Śiva-sūkta, et aussi avec l’auspicieux mantra Tryambaka, on doit ensuite réciter le Tvarita-Rudra ainsi que le Śiva-saṅkalpa—achevant ainsi le membre mantrique de l’adoration de Śiva, qui mène le paśu (l’âme liée) vers le Pati (Seigneur).
Suta Goswami (narrating Shiva-puja procedure to the sages of Naimisharanya)
It specifies the mantra-sequence within Linga-puja—Śiva-sūkta, Tryambaka, Tvarita-Rudra, and Śiva-saṅkalpa—showing that worship is completed not only by offerings but by Vedic recitation and inner resolve directed to Pati (Śiva).
Śiva is invoked as Tryambaka and Rudra—the auspicious yet sovereign Lord who purifies bondage (pāśa) through mantra, drawing the paśu toward His grace and right orientation (saṅkalpa) in worship.
Mantra-japa as a limb of Śiva-puja: disciplined recitation (japa) of Rudra/Śiva mantras coupled with Śiva-saṅkalpa, aligning mind and breath toward Pāśupata purification and devotion.
