"The nearer we are to [beasts and] birds, the more we are in the hells of emotion. We call it love. It is self-hypnotization. We are under the control of our [emotions] like animals. A cow can sacrifice its life for its young. Every animal can. What of that? .. What is the difference between men and animals? ...‘Food and [sleep], procreation of the species, and fear exist in common with the animals. There is one difference: Man can control all these and become God... Animals cannot do it." - Swami Vivekananda
