I’ve written a book about vegetarianism as a Buddhist practice, and you can read more about that book on this site.

Vegetarianism
by Bodhipaksa

“Using his description of the plight of farm animals as a launching point, Bodhipaksa expounds a vegetarian lifestyle from the point of view of metta or loving-kindness. Bodhipaksa provides a fresh, new examination of vegetarianism from a Buddhist perspective. While keeping the discussion out of the technicalities of academic debate, the author uses powerful arguments from professional and personal experience and a back-to-Buddhist-basics reasoning to make his case. This book represents an important contribution to this issue for those interested in the practical application of Buddhist vegetarianism in a modern, industrialized context.”
