Prabhupāda: Now here I am sitting, New York, a very great, the world's greatest city, so magnificent city, but my heart is always hankering after that Vṛndāvana.
Prabhupāda: Yes. I am not happy here.
Woman: Yes, I know.
Prabhupāda: I shall be very happy to return to my Vṛndāvana, that sacred place. "But then why you are . . .?" Now, because it is my duty. I have brought some message for you people. Because I am ordered by superior, my spiritual master, that "Whatever you have learned, you should go to the Western country, and you must distribute this knowledge."
So in spite of all my difficulties, all my inconveniences, I am here because I am in duty. I, I... that is my personal convenience: if I go and sit down at Vṛndāvana, I shall be very comfortable there, and I'll be... I'll have no anxiety, nothing of the sort. You see? But I have taken all the risk in the old age because I am in duty bound. I am in duty bound. So I have to execute my duty in spite of all my inconveniences. That is the idea.
