That is missionary activity, that they do not understand, but you have to make them understand. They are not calling you, “I am suffering. Please come,” but it is your business to go and let them know that “You are suffering. You take this method.” That is the way of becoming very quickly recognized by Krsna. Otherwise, if you think, “They are not understanding. What is the use of going there? Let me sleep,” that is not good. They are not understanding; still, you have to go. Then Krsna will take that “He is laboring so hard for My sake.” Never mind he is successful. It doesn’t matter. But you are working hard for Krsna. That is noted down. So our business is to be recognized by Krsna. Whether one man is converted or not converted, that is not our business. We shall try our best. But Krsna must see that I am giving service to Krsna. That’s all. That is wanted. Not that you have to judge that you have approached so many men; nobody became Krsna conscious. That doesn’t matter. But you have gone there.

You have endeavored your sincere effort. That is recognized by Krsna. That
is the order of Caitanya Mahaprabhu. Yare dekha, tare kaha ‘krsna’-upadesa [Cc Madhya 7.128]: “Whomever you meet, you give him, you inform him the instruction of Krsna.” Caitanya Mahaprabhu never said that “You see that he has actually become Krsna conscious.” Never says. You simply say and go and say. That is your business. It is not that you have to see that he has
become Krsna conscious. It is not so easy to become Krsna conscious. It is not so easy. It will take, bahunam janmanam ante [Bg 7.19], after many, many births. But you have to do your duty. Go and preach. Yare dekha, tare kaha ‘krsna’-upadesa [Cc Madhya 7.128]. Your duty is finished. Of course, you will try to convert him. If he is not converted, that is not deviation of your duty. You have to simply go and speak. Just like when I came to your country, I never expected any success because I knew, “As soon as I will say, ‘No illicit sex, no meat-eating,’ they will reject me immediately.” [laughter] So I was not hopeful at all.
