SB 6.2.11
na niskrtair uditair brahma-vadibhis
tatha visuddhyaty aghavan vratadibhih
yatha harer nama-padair udahrtais
tad uttamasloka-gunopalambhakam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
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.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Srila Visvanatha Cakravarti Thakura comments that the chanting of the holy name of the Lord has special significance that distinguishes it from the Vedic ritualistic ceremonies of atonement for severe, more severe or most severe sinful actions. There are twenty types of religious scriptures called dharma-sastras, beginning with the Manu-samhita and Parasara-samhita, but herein it is stressed that although one may become free from the reactions of the most sinful activities by following the religious principles of these scriptures, this cannot promote a sinful man to the stage of loving service to the Lord. On the other hand, chanting the holy name of the Lord even once not only frees one immediately from the reactions of the greatest sins, but also raises one to the platform of rendering loving service to the Supreme Personality of Godhead, who is described as uttamasloka because He is famous for His glorious activities. Thus one serves the Lord by remembering His form, His attributes and pastimes. Srila Visvanatha Cakravarti Thakura explains that this is all possible simply by chanting the Lord’s holy name because of the Lord’s omnipotence. What cannot be achieved through the performance of Vedic rituals can be easily achieved through the chanting of the Lord’s holy name. To chant the holy name and dance in ecstasy is so easy and sublime that one can achieve all the benefits of spiritual life simply by following this process. Therefore Sri Caitanya Mahaprabhu declares, param vijayate sri-krsna-sankirtanam: “All glories to Sri Krsna sankirtana!” The sankirtana movement we have started offers the best process for becoming purified of all sinful reactions and coming immediately to the platform of spiritual life.
