Pāśupata-vrata Māhātmya: Dvādaśa-Liṅga Mahāvrata, Month-wise Dravya, and Pūjā-krama
नीराजनाद्यैश्चान्यैश् च लिङ्गमूर्तिमहेश्वरम् अगरुं दक्षिणे दद्याद् अघोरेण द्विजोत्तमाः
nīrājanādyaiścānyaiś ca liṅgamūrtimaheśvaram agaruṃ dakṣiṇe dadyād aghoreṇa dvijottamāḥ
Sesudah melakukan nīrājana (ārati) dan upacara adat yang lain, hendaklah golongan dvija mempersembahkan agaru (kayu gaharu) yang harum kepada Maheśvara yang bersemayam dalam wujud Liṅga, meletakkannya di sebelah kanan, sambil melafazkan Aghora‑mantra, wahai yang terbaik antara Brāhmaṇa.
Suta Goswami (narrating Shiva-puja instructions to the sages of Naimisharanya)
It specifies an upacāra (service) in Liṅga-pūjā: after nīrājana (ārati), one should offer agaru fragrance to the Liṅga-Maheśvara, showing reverence through scent and right-sided placement as part of orderly ritual worship.
Shiva is affirmed as Pati—Maheśvara—present and worshipable as the Liṅga-mūrti, indicating that the transcendent Lord graciously assumes an iconic form so the pashu (bound soul) may approach Him through disciplined worship.
Mantra-guided pūjā is highlighted—specifically offering agaru while using the Aghora-mantra—linking external worship (upacāra) with inner purification, a Shaiva method for weakening pasha (bondage) and orienting the practitioner toward Shiva.
