Such are the effects of Krsna consciousness. If one somehow or other becomes Krsna conscious by applying his senses in the service of the Lord, one is immediately freed from material contamination. Srnvatam sva-kathah krsnah punya-sravana-kirtanah (Bhag. 1.2.17). Hearing about the activities of Krsna is the beginning of purified life. Punya-sravana-kirtanah: simply by hearing and chanting, one becomes purified. Therefore, in discharging devotional service, sravana-kirtana (hearing and chanting) is most important. Then, with purified senses, one begins to render service to the Lord (hrsikena hrsikesa-sevanam [Cc. Madhya 19.170]). Bhaktir ucyate: this is called bhakti. When Putana was somehow or other, directly or indirectly, induced to render some service to the Lord by feeding Him with her breast, she was immediately purified, so much so that when her nasty material body was burnt to ashes, it gave off the fragrance of aguru, the most agreeably scented herb.
