लिङ्गार्चनपूर्वकं स्नानाचमनविधिः
Snana–Achamana as Preparation for Linga-Archana
उद्धृतासीतिमन्त्रेण पुनर्देहं विशोधयेत् मृदादाय ततश्चान्यद् वस्त्रं स्नात्वा ह्यनुल्बणम्
uddhṛtāsītimantreṇa punardehaṃ viśodhayet mṛdādāya tataścānyad vastraṃ snātvā hyanulbaṇam
Using the mantra called “Uddhṛtāsīti,” one should again purify the body. Then, taking purifying earth (clay), and after bathing properly, one should put on another, clean and unsoiled garment.
Suta Goswami (narrating Śiva-pūjā-vidhi to the sages of Naimiṣāraṇya)
It establishes śauca (ritual purity) as a prerequisite for approaching the Liṅga: mantra-based purification, cleansing with earth, bathing, and wearing clean cloth so the worshipper becomes fit for Pati (Śiva) upāsanā.
By requiring deliberate purification before worship, it implies Śiva as Pati—the supremely pure consciousness—approached through disciplined removal of mala (impurity) in the pashu (bound soul), aligning the devotee with śuddhatā.
A preparatory pūjā-vidhi practice: mantra-śauca, mṛdā-śuddhi (cleansing with clay/earth), snāna (bath), and vastra-parivartana (changing into clean clothing), reflecting outer discipline that supports inner Pāśupata sādhanā.
