By following the Vedic ritualistic ceremonies or undergoing atonement, sinful men do not become as purified as by chanting once the holy name of Lord Hari. Although ritualistic atonement may free one from sinful reactions, it does not awaken devotional service, unlike the chanting of the Lord’s names, which reminds one of the Lord’s fame, qualities, attributes, pastimes and paraphernalia.
