One is the snake; another is the man snake, or a man habituated to the snake quality." So sarpaḥ krūraḥ khalaḥ krūraḥ. But Cāṇakya Paṇḍita said, "This man snake is more dangerous than the animal snake." Sarpāt krūrataraḥ khalaḥ. Why? Now, mantrauśādhi-vaṣaḥ sarpaḥ khalaḥ kena nivāryate: "You can subdue the snake by chanting a snake mantra or some drug, jadi-buti, but this man snake cannot be subdued." It is very, very dangerous.
So this is our position. Therefore a preacher devotee is so, I mean to say, favorite to Kṛṣṇa. They have to meet actually dangerous persons, krūraḥ persons. Just see. Jesus Christ, what fault he had? He was preaching about God, and he was crucified. Crucified. That is in your country a very good example. Simply his fault was he was talking of God, that's all, and he was crucified. So we have to meet. Our Nityānanda Prabhu, He also met that Jagāi-Mādhāi. Of course, He delivered them. Nityānanda Prabhu is so kind that in spite of being stroken and blood came out from His head, still, He continued to say, "My dear friends, never mind you have injured Me. You chant Hare Kṛṣṇa." So the preaching is so difficult thing. Therefore Kṛṣṇa said, na ca tasmān manuṣyeṣu kaścid me priya kṛttamaḥ (BG 18.69). It is not very sitting idly, comfortably, and discuss Vedānta. No. It is not like that. Preaching practically. Practically meeting dangerous position because sympathetic. Saṁsāra dāvānala. The whole world is in blazing fire. Para-duḥkha-duḥkhī. Vaiṣṇava is para-duḥkha-duḥkhī. And that is his qualification. For him there is no difficulty. He's quite all right. He's under the protection of Kṛṣṇa.
