Most of our preparations are made from milk products. Therefore we are so much fond of cow protection. It gives the basic principle of palatable foodstuff. But these people, they do not know. They simply cut the throat of the cow and boil it and with salt. [laughter] They do not know how to keep the cow and take milk from it and prepare hundreds and thousands of nice preparations.

That is a lack of civilization. Just like the aborigines, they find an animal, kill it and eat. They do not how to utilize the animals. Most aboriginal. We keep cows, we take milk, and from milk we make yogurt, we make ghee, and from ghee we prepare so many things.
