So preaching work, four vision—īśvare tad-adhīneṣu bāliśeṣu dviṣatsu ca (SB 11.2.46): God, Kṛṣṇa; His devotee; innocent; and the atheist. So we are concerned with three: with God, the devotees and the innocent: to love God, to make friendship with devotees and to teach the innocent. And those who are atheist, against God, avoid. Don't talk. Useless waste of time. Whatever he wants, "All right, sir, you are very great." That's all right. (laughter) (chuckles) Don't talk with them. Simply waste of time. But if one is inquisitive . . . just like this child, he wants to learn. As I say: "Oh, offer your obeisances," he does it. Oh, he should be taken care, very much developed.
But that is also one of the offenses, out of the ten offenses. One who is disinclined to understand what is this chanting, you should not bother yourself to convince him. That's all. Just like in hospital, especially in the war field, there are many wounded soldiers are coming. But the doctors see that the soldier which has got the chance of living, take care more for them. And the soldier which is immediately going to die, they do not take care much. Because it is useless; he'll not live.
Similarly the atheist, the atheist will have to suffer. They will have to meet God in the form of death in so many ways. So by suffering, suffering, suffering, suffering, suffering, when a day will come that he'll understand God, at that time, preaching to him is better. So you do not expect that our preaching will be appeal to everyone. It will be useful for the devotees, for the innocent. Not for the atheist.
So try to understand the philosophy very nicely, because you are going to preach. So many opposing elements will come. So you have to defend yourself. The more you can defend yourself from the opposing elements, the more you are advancing. You should know . . . that is the test. That is the test. Because you are preacher, so you have to test yourself, how you are making advance. Don't be self-complacent, "Oh, I am very . . . I have advanced very much." Your advancement will be tested when you can meet opposing elements. Not that when the opposing elements come, "Oh, let him talk with Guru Mahārāja, or spiritual master." Why? What for you are being taught?
So you should be very careful to understand the philosophy. Otherwise, you are not making progress. Progress means you shall defend yourself from the opposing elements. That is progress.
