しかしカルパに通じた者たちのうち最上の、あらゆる儀軌に最も熟達した者は、このようにアーチャマナ(ācamana、浄めの含嗽)を行い、みずからのためにダルバ草(darbha)の束を敷き、シヴァ礼拝の儀の座を整える。
Suta Goswami (narrating to the sages of Naimisharanya)
It highlights the mandatory preparatory discipline—ācamana and establishing a darbha seat—showing that Linga-pūjā begins with ritual and inner purification before approaching Pati (Śiva).
By stressing purity and correct vidhi, it implies Śiva-tattva as Pati—the supremely pure Lord—approached through śuddhi (purification) and niyama (observance), which loosen pāśa (bondage) upon the paśu (embodied soul).
Ācamana (purificatory sipping) and the use of darbha grass as an āsana for worship—outer supports that correspond to inner śauca (purity) in a Pāśupata-oriented approach to Śiva-pūjā.
