May we all receive Srila Prabhupada's mercy
And work together to spread Krishna Consciouness
Simply by associating with a pure devotee, one becomes wonderfully advanced in Krsna consciousness. Sadhu-sanga, or association with a devotee, means always engaging in Krsna consciousness by chanting the Hare Krsna mantra and by acting for Krsna.
Specifically, chanting the Hare Krsna mantra purifies one, and this chanting is therefore recommended by Sri Caitanya Mahaprabhu.
Ceto-darpana-marjanam: by chanting the names of Krsna, the mirror of the heart is cleansed, and the devotee loses interest in everything external. When one is influenced by the external energy of the Lord, his heart is impure. When one's heart is not pure, he cannot see how things are related to the Supreme Personality of Godhead.
Idam hi visvam bhagavan ivetarah(Bhag. 1.5.20). He whose heart is purified can see that the whole cosmic manifestation is but the Supreme Personality of Godhead, but he whose heart is contaminated sees things differently.Therefore by sat-sanga, or association with devotees, one becomes perfectly pure in heart.
