Kapag ang tao ay humipo sa mga bagay na marumi at di-mapalad para sa tao—gaya ng tubig na naalog mula sa dulo ng kuko at buhok, o tubig mula sa pamunas sa paliligo at sa sisidlan ng paliligo—ang paghipong iyon ay dapat ituring na aśuddha (ritwal na karumihan), na humahadlang sa pagpapala na kailangan sa pagsamba kay Śiva.
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.
