Those who have accepted the task of spreading the Hare Krsna maha−mantra in full Krsna consciousness should take this opportunity to deliver people very easily from the clutches of material existence. Our duty, therefore, is to follow the instructions of Sri Caitanya Mahaprabhu and preach the Krsna consciousness movement all over the world very sincerely. This is the best welfare activity for the peace and prosperity of human society.
The chanting of the holy name is Lord Caitanya's special concession to the animallike human beings of this age: Love of Krsna is not an easy thing to obtain, because by this love one can purchase Krsna, but Caitanya Mahaprabhu distributed this love of Krsna to anyone and everyone, even to the two drunkards Jagai and Madhai. Narottama dasa thakura has therefore sung:
dina−hina yata chilo hari−name uddharilo,
ta'ra saksi jagai−madhai
"Caitanya Mahaprabhu is so magnanimous that He delivered all kinds of sinful men simply by allowing them to chant the Hare Krsna mantra. The evidence of this is Jagai and Madhai."
At that time, of course, there were two Jagais and Madhais, but at the present moment, by the grace of Caitanya Mahaprabhu and His process of teaching, so many Jagais and Madhais are being delivered. If Caitanya Mahaprabhu is pleased, He can give krsna−prema, love of Krsna, to anyone, regardless of that person's qualification. If a person is giving charity, he can select anyone to take it.
Without the mercy of Caitanya Mahaprabhu, understanding Krsna is very, very difficult. Manusyanam sahasresu kascid yatati siddhaye (Bg. 7.3): out of many millions of people, hardly one tries to make his life spiritually successful. People simply work like animals, not knowing how to make a success of human life. One's human life is successful when one understands Krsna; otherwise one remains an animal. Anyone who is not Krsna conscious, who does not know who Krsna is, is no better than an animal. But Caitanya Mahaprabhu gave this concession to the fallen souls of this age: "Simply chant the Hare Krsna maha−mantra and you will be delivered." This is Caitanya Mahaprabhu's special concession (kirtanad eva krsnasya mukta−sangah param vrajet, S.B. 12.3.51).
