According to Vedas, cow is earth representative and ox is a simbol of religion principles. Lord Krishna Himself, when he came to this world, had poinetd out how much he loves cows and cares for their protection. When the ox and cow are satisfied, people in the world are satisfied too. Ox helps in cereals production, and cow gives us milk and so many other milk products. In that way, human society becomes enlarged economicaly and in that simple living man shouldn´t have economical problems.
The goal of cow protection is a peace of mankind. Extremely sinful act of cow killing is cause of all kinds of troubles. In vedic society, cow is considered to be the one of our mothers because she nourishes us with her milk. So we have 7 persons which we have to respect as our own mother..One of them is a cow, and other are our biological mother, mother Earth, mother of a guru etc... That´s why cow killing is a very sinful activity, practically the same thing like if you kill your own mother. People are not conscious what are they doing in the name of economical development. By establishing cow protection we will relieve ourselves from ecological and social problems, which will also help us to create spiritual and peaceful earth for the future.
Srila Prabhupada said: „ We want to disenable a sloughter houses conservation. It is very sinful activity. In Europe there are so many wars. Very 10-15 years there is a war, massacre of all humankind. The leaders of society don´t see this. But the reaction is necessary. The nature will take revenge.“
