Śrīmad-Bhāgavatam · Text 11.2.12
Who is speaking and story frame
श्रुतोऽनुपठितो ध्यात आदृतो वानुमोदित: ।
सद्य: पुनाति सद्धर्मो देव विश्वद्रुहोऽपि हि ॥ १२ ॥
śruto ’nupaṭhito dhyāta
ādṛto vānumoditaḥ
sadyaḥ punāti sad-dharmo
deva-viśva-druho ’pi hi
Pure devotional service rendered to the Supreme Lord is spiritually so potent that simply by hearing about such transcendental service, by chanting its glories in response, by meditating on it, by respectfully and faithfully accepting it, or by praising the devotional service of others, even persons who hate the demigods and all other living beings can be immediately purified.
