Srimad Bhagavatham : 6.2.12.
naikantikam tad dhi krtepi nishkrte
manah punar dhavati ced asat-pathe
tat karma-nirharam abhipsatam harer
gunanuvadah khalu sattva-bhavanah.
na = not;
aikantikam = absolutely cleansed;
tat = the heart;
hi = because;
krte = very nicely performed;
api = although;
nishkrte = atonement;
manah = the mind;
punah = again;
dhavati = runs;
cet = if;
asat-pathe = on the path of material activities;
tat = therefore;
karma-nirharam = cessation of the fruitive reactions of material activities;
abhipsatam = for those who seriously want;
hareh = of the Supreme Personality of Godhead;
guṇa-anuvādaḥ—constant chanting of the glories;
khalu = indeed;
sattva-bhavanah = actually purifying one’s existence.
The ritualistic ceremonies of atonement recommended in the religious scriptures are insufficient to cleanse the heart absolutely because after atonement one’s mind again runs toward material activities. Consequently, for one who wants liberation from the fruitive reactions of material activities, the chanting of the Hare Krishna mantram, or glorification of the name, fame and pastimes of the Lord, is recommended as the most perfect process of atonement because such chanting eradicates the dirt from one’s heart completely.
