Kế đó, theo đúng thứ tự, hành giả nên rửa sạch đầu ngón tay của cả hai bàn tay, tẩy sạch đôi chân và thực hành ācamana; trở nên thanh tịnh, thu nhiếp nội tâm, an trụ điềm tĩnh để phụng thờ Pati—Đức Chúa Śiva.
Suta Goswami (narrating Shiva-puja procedure to the sages at Naimisharanya)
It establishes śauca (ritual cleanliness) and mental steadiness as prerequisites for Linga-pūjā—purifying the senses and body so the worshipper approaches Pati (Śiva) with disciplined reverence.
By implying that Śiva is approached through purity and samāhita-citta (collected awareness), the verse aligns with Shaiva Siddhānta: the bound pashu turns toward Pati by reducing pasha—impurity and distraction—before worship.
Ācamana and preparatory washing (hands, fingertips, feet) are paired with samādhāna (mental composure), showing the union of karma (ritual discipline) and yoga (inner concentration) in Shiva-pūjā.
