ನಖಗಳ ತುದಿ ಹಾಗೂ ಕೂದಲ ತುದಿಯಿಂದ ಜಾರಿದ ನೀರು, ಸ್ನಾನವಸ್ತ್ರದ ನೀರು, ಸ್ನಾನಘಟದ ನೀರು—ಇವು ಮಾನವರಿಗೆ ಅಶ್ರೀಕರ; ಇವನ್ನು ಸ್ಪರ್ಶಿಸಿದರೆ ಆ ಸ್ಪರ್ಶ ಅಶುದ್ಧವೆಂದು ತಿಳಿಯಬೇಕು।
Suta Goswami
It sets a śauca standard for approaching the Liṅga: contact with discarded bathing water (from nails, hair, cloth, or pot) is treated as aśuddha, since Śiva-pūjā requires auspiciousness and careful handling of sanctified substances.
By implication, Śiva as Pati is approached through order (vidhi) and purity: the soul (paśu) bound by impurities (pāśa) must remove external and internal taints; ritual discipline mirrors the deeper purification needed to align with Śiva-tattva.
Ritual śauca: avoiding contact with impure remnants of bathing and maintaining cleanliness around worship materials; as a yogic takeaway, it points to disciplined purification as a prerequisite for Pāśupata-oriented sādhana.
