ഇവർ (അശുചികൾ) പുരുഷനെ സ്പർശിച്ചാൽ അവന്റെ സഞ്ചിത പുണ്യം ഹരിക്കുന്നു—ഉഷ്ണീഷധാരി, കഞ്ചുകധാരി, നഗ്നൻ, മുക്തകേശൻ, മലാവൃതൻ.

It stresses śauca (ritual and inner purity) as a prerequisite for Linga-pūjā; unclean contact and disorderly appearance are treated as obstacles that weaken sukṛta and thus reduce one’s fitness (adhikāra) for Shiva’s worship.
By implication, Shiva as Pati is approached through disciplined purity; when the pashu remains entangled in pāśa-like impurity and negligence, its merit and clarity decline, delaying steady orientation to Shiva-tattva.
Śauca-niyama (cleanliness and regulated conduct) supporting pūjā and Pāśupata-oriented sādhanā—maintaining bodily and mental order so merit is preserved and the mind remains fit for japa, vrata, and worship.
