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.
