Some info about vegetarianism, and a whole bunch of quotes that brought tears to my eyes. A few:
Nothing will benefit human health and increase chances for survival of life on Earth as much as the evolution to a vegetarian diet. -- Albert Einstein.
All creation has the same right to life.
Whenever we cause suffering or death to any other being, we cause suffering to the Great Life Force. -- Shik Po Chih.
Thou shall not kill.
Animals are my friends--and I don't eat my friends. -- George Bernard Shaw.
The greatness of a nation and its moral progress can be judged by the way its animals are treated. -- Mohandas Gandhi.
Whatever you do unto the least of my brothers, you do it unto me.
We stopped eating meat many years ago. During the course of a Sunday lunch we happened to look out of the kitchen window at our young lambs playing happily in the fields.
Glancing down at our plates, we suddenly realized we were eating the leg of an animal who had until recently been playing in a field herself. We looked at each other and said: "Wait a minute, we love these sheep - they're such gentle creatures. So why are we eating them?" It was the last time we ever did. -- Paul and Linda McCartney
I went snorkeling and noticed how gently the fish welcomed us into their world ... as compared to the violence with which we welcomed them into ours. I became a vegetarian.
"I would not eat if no one kills the animal", said the meat eater. "I would not kill if no one eats the animal", said the butcher.
Of what use are all your sacrifices to Me? I have had enough of the roasted carcasses of rams and of the fat of fattened beasts. I take no pleasure in the blood of calves, lambs and goats. ... When you spread out your hands, I close My eyes to you; despite however much you pray, I will not listen. Your hands are full of blood! Wash yourselves clean! Put away your misdeeds from before My eyes and stop doing evil. -- Isaiah 1:11, 15-16.
Once I was fishing and caught the hook in the fish's eye. That was the last time I ate a killed creature.
Your body is not a grave yard.. you were not created to eat meat. This causes immense suffering. -- Robert Adams, Ramana devotee
You cannot become Awakened while you are causing suffering to others. -- Robert Adams
