Anyone who is Kṛṣṇa conscious, it is the duty to distribute it. It is his duty. You may... When I came here, I never came here because American boys or people wanted me. They did not feel any need of my presence. But I came here, because it is my duty. My Guru Mahārāja ordered me. So one may think there is need or no need—it is the duty of Kṛṣṇa conscious persons to spread it.
Just like the example I have already given. The cloud..., the mountain does not want rain, the sea does not want, but the cloud throws water everywhere."
