Wasser, das man auf der Erde findet, gilt für die Verehrung als rein—besonders jenes, aus dem eine Kuh bis zur vollen Sättigung trinken kann. Wasser, das nicht von Unreinem berührt ist und angenehmen Duft, Farbe und Geschmack besitzt, ist geeignet, im Ritus Śivas dargebracht zu werden.
Suta Goswami (narrating the Shiva-puja standards as taught in the Linga Purana tradition)
It defines the practical standard for abhiṣeka water: it must be naturally pure, unpolluted, and pleasing—so the offering to Pati (Śiva) is made with śauca (ritual purity) and reverence.
By insisting on purity and untainted offerings, it implies Śiva as Pati—the supremely pure consciousness—approached through disciplined purification of the pashu (soul) from pasha (impurity and defilement).
Ritually, it highlights selecting suitable water for Śiva-abhiṣeka. Yogically (Pāśupata spirit), it underscores external śauca as a support for inner purification and steadiness in worship.
