सर्व एव यजन्ति त्वां सर्वदेवमयेश्वरम् ।
येऽप्यन्यदेवताभक्ता यद्यप्यन्यधिय: प्रभो ॥ ९ ॥

sarva-deva-mayeśvaram
ye ’py anya-devatā-bhaktā
yady apy anya-dhiyaḥ prabho
But all these people, my Lord, even those who have turned their attention away from You and are worshiping other deities, are actually worshiping You alone, O embodiment of all the demigods.
