Water found upon the earth is considered pure for worship—especially that from which a cow may drink to her full satisfaction. Water untainted by impure substances, and possessing agreeable fragrance, color, and taste, is fit to be offered in Śiva’s rite.
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.
