उपलेपनादिकथनम्
Vastraputa-jala, Ahimsa, and Conduct in Shiva Worship
ये पुत्रपौत्रवत्स्नेहाद् रुद्रलोकं व्रजन्ति ते तस्मात्सर्वप्रयत्नेन वस्त्रपूतेन वारिणा
ye putrapautravatsnehād rudralokaṃ vrajanti te tasmātsarvaprayatnena vastrapūtena vāriṇā
Quienes, con afecto como el que se tiene por hijos y nietos, alcanzan el mundo de Rudra—por eso, con todo empeño, úsese agua purificada al filtrarla con un paño (para el servicio y la adoración).
Suta Goswami (narrating to the sages of Naimisharanya)
It stresses dravya-shuddhi (purity of offerings): even water should be cloth-filtered, showing that careful, reverent worship of the Linga supports attainment of Rudraloka.
Shiva is implied as Pati (the Lord) whose loka is reached not merely by ritual, but by tender, familial devotion (putra-pautra-vat-sneha), indicating grace responding to bhakti joined with purity.
A key puja-practice is highlighted: offering vastrapūta-vāri (cloth-filtered water), reflecting outer purity that supports inner purification central to Shaiva sadhana and Pashupata discipline.
