Quotes

Those who, by their purchases, require animals to be killed have no right to be shielded from the slaughterhouse or any other aspect of the production of the meat they buy. If it is distasteful for humans to think about, what can it be like for the animals to experience it?

A human being is a part of the whole, called by us the 'Universe', a part limited in time and space. He experiences himself, his thoughts and feelings, as something separate from the rest - a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security.

Not the suffering and death of the animals, but that man suppresses in himself unnecessarily, the highest spiritual capacity - that of sympathy and pity towards living creatures - and by violating his own feelings, becomes cruel. And how deeply seated in the human heart is the injunction not to take life. But by the assertion that God ordained the slaughter of animals, and above all as a result of habit, people entirely lose their natural feeling.
