The idea of eating sentient beings is appalling to me. For example, while the first noble truth says that "all life entails suffering" ; there are in addition the concepts of "karuna" and "maitri" that support alleviating the suffering of sentient beings. Along with tenets of the eightfold path that say "right action" and "right livelihood" are important to the Buddhist path. It so easy for the human animal to ignore the suffering of non-human animals. Oh and please do remember that your mother may have reincarnated as a non-human being and you may be eating her.
