purification after touching a dead body spṛṣṭvā pretaṃ trirātreṇa dharmārthaṃ snānamucyate dāhakānāṃ ca netṝṇāṃ snānamātramabāndhave
触及尸身之后,为护持法(dharma),当行净浴并守净三夜。至于焚尸者与抬送、引领尸身至火葬处者,若非亲属,则唯以沐浴即可得净。
Suta Goswami (narrating Linga Purana teachings to the sages of Naimisharanya)
It defines śauca (ritual purity) after contact with death, a prerequisite for approaching Shiva-Linga worship with proper adhikāra (eligibility) and maintaining dharma in ritual life.
Indirectly, it presents Shiva as Pati who is approached through dharmic discipline: purity rules regulate the embodied pashu so that worship is performed with inner and outer order, reducing pāśa (impurity/bondage) that obstructs devotion.
Śauca via snāna (purificatory bathing) and time-bound purification after contact with a corpse—practical dharma that supports correct Shiva-puja and steadiness in sādhana.
