Prabhupāda: Oh, yes. Cow protection protects us from so many infectious disease.
Dr. Sharma: Even the cows, they have habit to take the weeds along the banks of the river. The iodine content of the grass is so high. It has got iodine in that. So if we smear cow dung on the floor, it is said it is an obnoxious thing, whereas tincture of iodine is sold in the shops . . . (indistinct) . . . I'm sure that it is sold very well. It is most unfortunate that we do not appreciate the nature itself is giving us aids.
Prabhupāda: We take it seriously, because Kṛṣṇa says. Kṛṣṇa is our authority. He says, kṛṣi-go-rakṣya. Go-rakṣya: "You must give protection to the cows." This is authority.
Dr. Sharma: When we talk about civil liberties and rights in democratic countries today, but we have a right to live on this planet. Why should we differate the right of another animal which cannot express itself?
Prabhupāda: They are . . . They are . . . They are described in the Bhāgavata, pāpinaḥ. Those who are killing other animals for maintaining his own body, they are very, very sinful. Very, very sinful. Therefore untouchable. According to Vedic civilization, the animal-killers, mlecchas, they are untouchable. They are so sinful.
Dr. Sharma: They talk about killing of animals for wants of survival. Darwin's case has been brought in, put in, survival, struggle for existence. I mean to have a talk with Doctor yesterday. Even the key of the evolution theory by Darwin, he is not feeling itself. It has lots of blemishes.
Prabhupāda: He has described in his book, Darwinism. What? What you have described?
Svarūpa Dāmodara: It is . . . His knowledge is based on some simple speculation.
Prabhupāda: Speculation. It is not sound knowledge.
Dr. Sharma: He says that the giraffe has got a very lengthy neck because there was no grass on the floor. He had to reach the branches and boughs of a tree for the leaves. So he had a lengthy neck.
Prabhupāda: So who made this arrangement?
Dr. Sharma: It was written by Darwin, the great man.
Prabhupāda: No, that's all right, but next question will be, "Who made his neck so long? Why not your neck?"
Dr. Sharma: Then Darwin forgot there are millions of other herbivores living on the planet.
Prabhupāda: He's a nonsense.
Dr. Sharma: They did not develop a big neck. Only giraffe developed, because Darwin wanted it.
Prabhupāda: (laughs) Therefore he's a nonsense. He has . . .
Dr. Sharma: (indistinct) . . . that we all learn by heart, we are being obsessed by our own thing. We don't seem to observe the creed of life.
Prabhupāda: Less intelligent. Therefore it is our duty to educate them, out of sympathy. That is Caitanya Mahāprabhu's mission. Paścimera loka saba mūḍha anācāra (CC Adi 10.89): "The Western peoples, they are mūḍhas and anācāras." So this mission is paropakāra, to give them knowledge and how to become civilized. This is the mission.
