Prabhupada's lecture - Śrīmad-Bhāgavatam 1.10.4 - Mayapura, June 19, 1973
Now here is very important word, that payasodhasvatīr mudā, udhasvatīr mudā. They were very jolly because they can understand whether they are going to be killed or not. Because they have got, they're animal, they have got sense. I have seen in your country, almost all cows are crying, crying. Because in the beginning, all the calves are taken away and slaughtered in their presence. Perhaps you know. So what is the position of the cow? I have seen when we purchase cows, the calves are already taken away. The cow was crying, regular tears were gliding down. So they can understand that... Who cannot understand? Suppose if you are taken in the concentrated camp? Just like the Germans did. What is the meaning of concentrated...? That he'll be killed after some days. So how you can be happy? If you are already informed, condemned to death, and kept in a concentration camp, will you be happy? Similarly, when these people take these cows to the slaughterhouse, animal stock room, go down, they understand. Very recently, about few years ago, some..., that animal stock store was some way or other broken and all the cows began to... Perhaps you know. It was published in the... And they were shot down. Shot to death. They were fleeing like anything, that "We shall save ourselves."
So if the cows are not happy, if they are always afraid, that "This rascal will kill us at any moment," then how they can be happy? There was no such thing. Therefore it is said: mudā. Mudā. Happy. And as soon as the cows are happy, you not only get sufficient milk, but the pasturing ground, I mean to say, ground, becomes moist with milk. So much milk supplied. Here it is stated, payasā udhasvatīr mudā. Yes. There is another description. Formerly, Kṛṣṇa's cows, when they were passing on, the whole road will be moistened with milk. Milk supply was so sufficient. Simply manufacture butter, milk products, dahi... Distribute. Kṛṣṇa was distributing amongst the monkeys even: "Take," the monkey, "come on."
So by Kṛṣṇa's grace if we actually become dharmic, follow Kṛṣṇa, the milk supply will be so profuse that everyone, even the animals can take the butter and yogurt. That is wanted. That is civilization. Produce sufficient quantity of grains, let the milk, cows, supply sufficient quantity of milk. All economic question solved. There is no use of industry. No use of man's going fifty miles to work. No, there is no need. Simply land and cows. Here is the statement. Kāmaṁ parjanyaḥ, vavarṣa parjanyaḥ sarva-kāma-dughā. Everything you'll get from the land. Even luxury articles. What can be more luxurious article than the jewels? The jewels are also produced. The medicine is produced, the minerals are produced, gold is produced, diamond is produced from the earth. Sarva-kāma-dughā. You get everything. Make your civilization very perfect, very luxurious simply by satisfying Kṛṣṇa. This is Kṛṣṇa consciousness movement.
