The holy name is more effective when chanted with faith. I often use the example that because the holy name has been given to us through the lips of Krishna's pure devotee, it is imbued with all the necessary potency to manifest Krishna-prema, pure love of God. I have that deep confidence, the firm faith in Srila Prabhupada's empowerment to deliver the holy name – that he is kali kalera dharma Krishna nama-sankirtana Krishna sakti vina nahe tara pravartana
