यजुषां परिमृज्यैवं द्विः प्रक्षाल्य च वारिणा प्रीत्यर्थं सामवेदानाम् उपस्पृश्य च मूर्धनि
yajuṣāṃ parimṛjyaivaṃ dviḥ prakṣālya ca vāriṇā prītyarthaṃ sāmavedānām upaspṛśya ca mūrdhani
Thus, after wiping oneself in accordance with the Yajur‑vedic procedure and washing twice with water, one should, for the delight of the Sāma‑Veda, touch that sanctified water to the crown of the head—thereby completing inner and outer purification before approaching the worship of Pati, Lord Śiva.
Suta Goswami
It prescribes the preparatory śauca (purification) sequence—Yajur-based cleansing, washing twice, and touching sanctified water to the crown—so the worshipper approaches the Liṅga with ritual and inner fitness, removing pasha-like impurities before seeking Pati’s grace.
By emphasizing purification before worship, it implies Śiva as Pati—the supremely pure Lord—approached through disciplined refinement of the pashu (individual soul) so that bondage (pāśa) is attenuated and receptivity to Śiva’s anugraha (grace) increases.
A Vedic-style ācamana/śuddhi practice: cleansing and washing, then applying sanctified water to the crown (mūrdhan), aligning body-mind for Śiva-pūjā in a Pāśupata spirit of purity and restraint.
