Truly, the killing of animals and the eating of their meat
is somewhat contrary to pity and compassion, and if one can content oneself
with cereals, fruit, oil and nuts, such as pistachios, almonds and so on, it
would undoubtedly be better and more pleasing.
('Abdu'l-Bahá, from a Tablet; The Compilation of Compilations, vol. I, Some
Aspects of Heath, Healing, Nutrition and Related Matters)
