dhanya aho ami alyo
yan brahmesau rama devi
dadhur murdhny agha-nuttaye
O girls! The dust of Govinda’s lotus feet is so sacred that even Brahma, Siva and the goddess Rama take that dust upon their heads to dispel sinful reactions.
According to Srila Visvanatha Cakravarti, who quotes from sastra, each day in the late afternoon, as Krsna returned from the cow pastures with His cowherd boyfriends, great demigods like Brahma and Siva would come down from heaven and take the dust of His feet.
Great personalities like the goddess Rama (the wife of Visnu), Siva and Brahma are not at all sinful. But in the ecstasy of pure Krsna consciousness they feel themselves fallen and impure. Thus, desiring to purify themselves, they blissfully take the dust of the Lord’s lotus feet on their heads.
