I'm ploughing my way through Shabkars 'Food of the Bodhisvatas' at the moment but I now feel inspired enough to get some books on MT and learn some more about her.
My opinion, as it stands, is that MT's state of 'enlightment' is as close to the descriptions of what constitutes the nature of an Aharant as matters and that she was, at the least, a full blown Bodhisattva I have absolutely no personal doubts.
Selfishness is thus virtualy impossible in my mind as far as MT is concerned.
Indisputably (yes, yes, I know that absolutely nothing actualy ever is ...) adopting a vegan diet and opposing the eating of meat (had she fully understood all the ramifications) would have been a tiny thing in comparison to the other personal sacrifices she made on behalf of the poor.
I'm particularly thinking that if the woman had ever fully seen the causual link between meat eating (particularly in the west) and the poverty where she did her work that she would have spoken with the same passion for veganism as she did for the pro-life cause.
I simply have to to assume, in the abscence of more detailed knowledge, that on the meat eating front MT never fully joined up all the dots, as it were.
