स्नानं विधानतः सम्यक् पश्चाद् आभ्यन्तरं चरेत् आ देहान्तं मृदालिप्य तीर्थतोयेषु सर्वदा
snānaṃ vidhānataḥ samyak paścād ābhyantaraṃ caret ā dehāntaṃ mṛdālipya tīrthatoyeṣu sarvadā
विधानतः सम्यक् स्नानं कृत्वा पश्चादाभ्यन्तरशौचं चरेत्। आ देहान्तं मृदालिप्य तीर्थतोयेषु सर्वदा स्नायात्॥
Suta Goswami (narrating Shiva-puja preparatory discipline to the sages of Naimisharanya)
It establishes śauca—outer bathing and inner purification—as the prerequisite that makes the paśu (individual soul) ritually and spiritually fit to approach the Linga, the presence-sign of Pati (Śiva).
Śiva is implied as Pati—the supremely pure Lord—so the aspirant aligns with that purity through disciplined cleansing, moving from external cleanliness toward inner transformation.
A Shiva-puja preparatory practice: prescribed snāna using cleansing earth (mṛdā) and bathing in tīrtha waters, followed by ābhyantara-śauca (inner purification) consistent with Pāśupata discipline.
