The pioneer of varnasrama and cow protection in the west!
His Divine Grace A.C. Bhaktivedanta Swami Prabhupada, came to America's shores in 1966, at the age of seventy. With neither help nor money initially, he gradually attracted some students and disciples, and with their help started spiritual farm communities thorughout the world, emphasizing the importance of cow protection.
Srila Prabhupada: "Human society needs only sufficient grain and sufficient Cows to solve its economic problems. All other things but these two are artificial necessities created by man to kill his valuable life at the human level and waste his time in things which are not needed. Lord Krishna, as the teacher of human society, personally showed by His acts that the mercantile community, or the vaisyas or business or trading community, should herd Cows and Bulls and thus give protection to these valuable animals. According to smrti regulation, the Cow is the mother and the Bull the father of the human being. The Cow is the Mother because just as one sucks the breast of one's Mother, human society takes Cow's milk. Similarly, the Bull is the Father of human society because the Father earns for the children just as the Bull tills the ground to produce food grains. Human society will kill its spirit of life by killing the Father and the Mother." - Srimad Bhagavatam 3.2.29 purport
