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.
