By associating with persons for whom the Supreme Personality of Godhead, Mukunda, is the all in all, one can hear of His powerful activities and soon come to understand them. The activities of Mukunda are so potent that simply by hearing of them one immediately associates with the Lord. For a person who constantly and very eagerly hears narrations of the Lord's powerful activities, the Absolute Truth, the Personality of Godhead in the form of sound vibration, enters within his heart and cleanses it of all contamination. On the other hand, although bathing in the Ganges diminishes bodily contaminations and infections, this process and the process of visiting holy places can cleanse the heart only after a long time. Therefore who is the sane man who will not associate with devotees to quickly perfect his life?

(Srila Prabhupada's translation of Srimad-Bhagavatam 5.18.11, spoken by Prahlada Maharaja)
