One has to be empowered by the Lord to spread devotional service. Otherwise it will not be possible. Therefore we have to constantly beg for His Mercy. CC Antya 7.11 says: kali-kalera dharma–krsna-nama-sankirtana, krsna-sakti vina nahe tara pravartana. “The fundamental religious system in the Age of Kali is the chanting of the holy name of Krsna. Unless empowered by Krsna, one cannot propagate the sankirtana movement.”
