व्यपोहनस्तवनिरूपण-प्रसङ्गे नक्तभोजन-शिवव्रतविधिः (वार्षिक-प्रतिमास-क्रमः)
क्षीरषष्टिकभक्तेन सम्पूज्य वृषभध्वजम् पौर्णमास्यां घृताद्यैस्तु स्नाप्य पूज्य यथाविधि
kṣīraṣaṣṭikabhaktena sampūjya vṛṣabhadhvajam paurṇamāsyāṃ ghṛtādyaistu snāpya pūjya yathāvidhi
पौर्णिमा के दिन क्षीर-षष्टिक अर्पण से वृषभध्वज भगवान् शिव की विधिपूर्वक पूजा करे। फिर घृत आदि से स्नान कराकर, नियमानुसार पुनः पूजन करे।
Suta Goswami (narrating Śiva-pūjā-vidhi to the sages of Naimiṣāraṇya)
It specifies a Paurṇamāsī (full-moon) procedure: offering milk-cooked śaṣṭika rice, performing abhiṣeka with ghee and related substances, and completing worship strictly by vidhi—presenting Linga/Śiva-pūjā as a regulated means to approach Pati.
By naming Him Vṛṣabhadhvaja, it points to Śiva as Pati—the sovereign Lord who is approached through sacred acts; ritual purity and devotion become instruments for the pashu to move away from pāśa toward Śiva’s grace.
Paurṇamāsī-vrata aligned Śiva-pūjā with abhiṣeka (snāna) using ghee and auspicious substances, plus a specific naivedya (kṣīra-ṣaṣṭika)—a discipline supportive of Pāśupata orientation through regulated worship.
