लिङ्गार्चनपूर्वकं स्नानाचमनविधिः
Snana–Achamana as Preparation for Linga-Archana
गन्धद्वारां दुराधर्षाम् इति मन्त्रेण मन्त्रवित् कपिलागोमयेनैव खस्थेनैव तु लेपयेत्
gandhadvārāṃ durādharṣām iti mantreṇa mantravit kapilāgomayenaiva khasthenaiva tu lepayet
Knowing the mantra, the adept should, while reciting the mantra that begins “gandhadvārāṁ durādharṣām,” smear the place of worship or the Linga-site with the dung of a tawny cow (kapilā), using only what is at hand.
Suta Goswami (narrating Shiva-puja procedure to the sages of Naimisharanya)
It prescribes ritual purification of the Linga-site through sanctifying plastering (lepa) with kapilā cow-dung while invoking a mantra, aligning outer cleanliness with the consecration required for Shiva-Linga worship.
By insisting on mantra-guided sanctification, it implies Shiva as Pati—approached through śuddhi and mantra-śakti—where the devotee (paśu) removes impurities that function as pāśa (bondage) before offering worship.
A puja-vidhi act of śauca (purificatory preparation) empowered by mantra-japa—an outer discipline that supports inner steadiness central to Shaiva sādhana and Pāśupata-oriented worship.
