(Krishna honoring the cow)
Prabhupāda: I have several times explained in this class that nobody has got any food problem. Simply the so-called civilized, advanced in science, these people have got problems of foodgrains. Otherwise, there are millions of elephants, they are eating very nicely. There are ants, there are elephants, there are tigers, there are monkeys, there are trees... So many, 8,400,000 forms of body. How they are eating? Unless they are eating... We kill animals, but the animals do not come to the..., to us, that "We are starving. Give us food." Never. By nature, there is arrangement, foodstuff. The cows, the other animals, they are eating grass. There is profuse growth of grass. So they are not eating your nice foodstuff, sandeśa, rasagullā. You are making sandeśa, rasagullā from the milk which they deliver. They are eating grass and delivering you nice foodstuff, milk. And from the milk, you can make hundreds and thousands of nice, nutritious, full of vitamin foodstuff. But no. We are so fool that instead of utilizing the milk, we are utilizing the blood. You see?
These rascals, the scientists, they do not know that milk is nothing but transformation of the blood. That everyone knows. So if you want to... That is nature's way, by God's will, that a cow gives forty pounds, fifty pounds milk daily, but it does not drink. Although it is her milk, no, it gives you, human society: "You take. But don't kill me. Let me live. I am eating only grass." Just see. And the civilized men killing them, killing them. And they want peace. Just see the fun. Without touching your foodstuff, the cow is eating the grass which is given by God, immense grass, and they are giving you the finest foodstuff, milk. Just after your birth you have only to drink milk, either mother's milk... Nowadays, mothers do not supply milk. That is also to be supplied by the cow. So from the very beginning of my life I am subsisting by the foodstuff given by mother, cow, and when I am grown up, I kill. This is my gratitude. Just see. And they are called civilized. Less than lowest animal, narādhama. They are called narādhama, lowest of the mankind. Those who are killing cows, maintaining slaughterhouse, they are lowest of the mankind. They are not human being. Less than animal. They have no gratitude.
So the idea is that there is no food problem. As the mother earth said to King Pṛthu that "I am restricting," so the more you become sinful, the food supply will be stopped. This is the law of nature. At the end there will be no foodgrains, at the end of Kali-yuga. That is stated in the Śrīmad-Bhāgavatam. There will be no foodgrain, no fruits, no milk, no sugar. You have to live on flesh and blood. At that time, being hungry, you will kill your own children and eat flesh and blood. That day is waiting. So this is the civilization. Most heinous civilization. It can only be saved by spreading this Kṛṣṇa consciousness movement. Otherwise there is no way. So sinful civilization.
