"Unless they smear upon their bodies the dust of the lotus feet of a Vaishnava completely freed from material contamination, persons very much inclined toward materialistic life cannot be attached to the lotus feet of the Lord, who is glorified for His uncommon activities. Only by becoming Krishna conscious and taking shelter at the lotus feet of the Lord in this way can one be freed from material contamination." (Prahlada Maharaja, Shrimad Bhagavatam, 7.5.32)
