लिङ्गार्चनविधिक्रमः—शुद्धि, न्यास, आसनकल्पना, अभिषेक, स्तोत्र-प्रदक्षिणा
Adhyaya 27
शुद्धिं कृत्वा यथान्यायं सितवस्त्रेण साधकः कुशापामार्गकर्पूरजातिपुष्पकचम्पकैः
śuddhiṃ kṛtvā yathānyāyaṃ sitavastreṇa sādhakaḥ kuśāpāmārgakarpūrajātipuṣpakacampakaiḥ
Having performed purification according to the prescribed rule, the practitioner—clad in a white garment—should proceed in worship with kuśa grass, apāmārga, camphor, jasmine blossoms, and campaka flowers.
Suta Goswami (narrating Shiva-puja procedure to the sages of Naimisharanya)
It establishes the prerequisite of śuddhi (ritual and inner purity) and specifies auspicious, purifying substances used to approach the Linga as Pati (Lord) with reverence and correctness.
By insisting on purity and prescribed order, it implies Shiva as Pati—the supremely pure consciousness—approached by the pashu (soul) through removal of pasha (impurity/bondage) symbolized by cleansing rites and sanctifying offerings.
A preparatory puja-vidhi: bodily and procedural purification, wearing clean white cloth, and using kuśa and apāmārga (expelling impurity) before mantra and Linga-upāsanā—supporting the Pāśupata emphasis on disciplined conduct.
