We must realize that violence is not confined to physical violence. Fear is violence, caste discrimination is violence, exploitation of others, however subtle, is violence, segregation is violence, thinking ill of others and condemning others are violence. In order to reduce individual acts of physical violence, we must work to eliminate violence at all levels, mental, verbal, personal, and social, including violence to animals, plants, and all other forms of life.
I find very reasonable the Celtic belief that the souls of our dearly departed are trapped in some inferior being, in an animal, aplant, an inanimate object, indeed lost to us until the day, which for some never arrives, when we find that we pass near the tree, or come to possess the object which is their prison. Then they quiver, call us, and as soon as we have recognized them, the spell is broken. Freed by us, they have vanquished death and return to live with us.
Plants, again, inasmuch as they are without locomotion, present no great variety in their heterogeneous pacts. For, when the functions are but few, few also are the organs required to effect them. ... Animals, however, that not only live but perceive, present a great multiformity of pacts, and this diversity is greater in some animals than in others, being most varied in those to whose share has fallen not mere life but life of high degree. Now such an animal is man.
Eating, drinking, dying - three primary manifestations of the universal and impersonal life. Animals live that impersonal and universal life without knowing its nature. Ordinary people know its nature but don't live it and, if they think seriously about it, refuse to accept it. An enlightened person knows it, lives it, and accepts it completely. He eats, he drinks, and in due course he dies - but he eats with a difference, drinks with a difference, dies with a difference.
