…On the spiritual path, there are several reasons why a person is recommended to be vegetarian. One primary reason is that we need to see the spiritual nature within all living beings, and that includes the animals and other creatures as well. Universal brotherhood means nonviolence to both humans and animals. It consists of understanding that animals also have souls. They are alive, conscious, and feel pain. And these are the indications of the presence of consciousness, which is the symptom of the soul.
…Isaac Bashevis Singer, who won the Nobel Prize in Literature, asked, “How can we pray to God for mercy if we ourselves have no mercy? How can we speak of rights and justice if we take an innocent creature and shed its blood?” He went on to say, “I personally believe that as long as human beings will go shedding the blood of animals, there will never be any peace.”
…The Buddhist scripture (Sutta-Nipata 393) also advises: “Let him not destroy or cause to be destroyed any life at all, or sanction the acts of those who do so. Let him refrain from even hurting any creature, both those that are strong and those that tremble in the world.” It is also said in the Buddhist scripture, the Mahaparinirvana Sutra, “The eating of meat extinguishes the seed of great compassion.”
