The person who has not at any time received the dust of the feet of the Lord's pure devotee upon his head is certainly a dead body and the person who has never experienced the aroma of the tulasi leaves from the lotus feet of the Lord is also a dead body, although breathing.
The dust of Krishna's lotus feet, which is the source of holiness for all places of pilgrimage, is worshiped by all the great demigods.
Prithu Maharaja is very emphatic in this connection — only an animal can give up the practice of chanting Hare Krishna. Those who are not animals but actually intelligent, advanced, human, civilized men cannot give up this practice of continually chanting Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare.
Purport on Srimad Bhagavatam 4.20.26
In this horrible condition of life there is only one way of liberation—to engage in the activities of transcendental chanting and hearing of the holy name of the Supreme Lord.
