Srimad Bhagavatam Canto 06, Chapter 03, Text 33

SB 6.3.33

krsnanghri-padma-madhu-lin na punar visrsta-
 maya-gunesu ramate vrjinavahesu
anyas tu kama-hata atma-rajah pramarstum
 iheta karma yata eva rajah punah syat
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Devotees who always lick the honey from the lotus feet of Lord Krsna do not care at all for material activities, which are performed under the three modes of material nature and which bring only misery. Indeed, devotees never give up the lotus feet of Krsna to return to material activities. Others, however, who are addicted to Vedic rituals because they have neglected the service of the Lord’s lotus feet and are enchanted by lusty desires, sometimes perform acts of atonement. Nevertheless, being incompletely purified, they return to sinful activities again and again.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
A devotee’s duty is to chant the Hare Krsna mantra. One may sometimes chant with offenses and sometimes without offenses, but if one seriously adopts this process, he will achieve perfection, which cannot be achieved through Vedic ritualistic ceremonies of atonement. Persons who are attached to the Vedic ritualistic ceremonies, but do not believe in devotional service, who advise atonement, but do not appreciate the chanting of the Lord’s holy name, fail to achieve the highest perfection. Devotees, therefore, being completely detached from material enjoyment, never give up Krsna consciousness for Vedic ritualistic ceremonies. Those who are attached to Vedic ritualistic ceremonies because of lusty desires are subjected to the tribulations of material existence again and again. Maharaja Pariksit has compared their activities to kuñjara-sauca, the bathing of an elephant.
