So however these men may declare very, very big, we know that "You have no brain. You are as good as animal." Therefore Bhāgavata says, śva-viḍ-varāhoṣṭra-kharaiḥ: [SB 2.3.19] "These classes of men are no better than the dogs, hogs, camels and asses." Bhāgavata school will not approve of these rascals as human being. They are so strict. If one is not on the platform of God consciousness, he is not human being. He is animal. That's a fact. But we should not hate the animals because our mission is to bring them to the human consciousness. You cannot expect that your audience should be all highly brain. No. Preaching is required because they have no brain. Therefore your duty is to tolerate all difficulties and bring them to the sense of brain. Not that "These people are animals; we shall not mix with them." Then you have no missionary activities. Then you sit down in a place and chant Hare Kṛṣṇa. Then don't open centers. That is also dangerous. If we imitate Haridāsa Ṭhākura, "Let us all chant and do nothing," then the māyā, the women, they are very expert. They could not conquer over Haridāsa Ṭhākura, but she'll conquer upon you. And become victim. Therefore we have to be active. We cannot imitate Haridāsa. Anyone who has imitated the Haridāsa Ṭhākura, he has fallen down. He has fallen. He must fall down because imitating the highest personality, for which he is not fit. Therefore he's going to fall down. When by preaching, by chanting, we will be expert, then it is possible.
