1. Powerful dust

    naisam matis tavad urukramanghrim
    sprsaty anarthapagamo yad-arthah
    mahiyasam pada-rajo-‘bhisekam
    niskincananam na vrnita yavat

    Unless they smear upon their bodies the dust of the lotus feet of a Vaisnava 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 Krsna conscious and taking shelter at the lotus feet of the Lord in this way can one be freed from material contamination.
