With lotus-seeds (padmākṣa), the merit is said to be ten lakhs; with golden offerings, it is said to be a koṭi (a crore). But with rudrākṣa beads strung with kuśa-knots, it is declared to yield merit of infinite multiplicity—because it is most intimate to the worship of Pati, Śiva, the Lord who loosens the bonds (pāśa) of the paśu (soul).

It ranks offerings by spiritual potency and declares rudrākṣa—especially when ritually strung with kuśa—as supremely effective for Śiva-bhakti and merit in Linga-pūjā.
By implying that what is dearest to Śiva (Pati) yields boundless fruit, it points to Shiva-tattva as the liberating Lord who removes pāśa (bondage) from the paśu (individual soul) through devotion and right observance.
