Have you visited much of these monasteries?
Usually if there’s enough monks there, the food arrangements is buffet. Even if the monks goes out for alms around, the food they bring back are arranged to become buffet selection.
When it’s buffet, it’s easy to become vegan. Well, unless it’s alms food from a region which has no vegans at all. That almost everyone eats meat in that locality.
For not having other monks convert you to become meat eaters, just don’t convert them, they don’t convert you, have some negative peace. Or don’t need to bring it up. Most important is just how your teacher sees it. Doesn’t matter if your teacher is vegan or not (actually it is very rare to find a vegan teacher), most important is that he is ok with you being vegan and wouldn’t convert you. The other monks attitude etc is secondary and can be worked on.
One way is that if they come to you again and again to say Buddha ate meat etc, sometimes, all it takes for them to back off is to do the standard vegan reasonings with them. For example, the Buddha didn’t live in this era of human induced climate change and industrial farming. Loving kindness extends to animals in cage due to being slaughtered. I don’t have any appetite for meat reflecting on that.
Not everyone is exposed to these kinds of reasonings because the older monks may had ordained before the internet and some monks from Myanmar and Sri Lanka may have been a novice since they are a kid.
So their exposure to the internet maybe that the vegan reasonings has not reached to them yet. But it’s more important to do it in a manner which is not defensive. So non violent communication course is a good way to do it.
A lot of the ones who wishes to change your diet may just opt for negative peace of you don’t remind them that they are making their stomach a graveyard for animal corpses, they don’t try to convert you away from veganism.
I only speak of why I am a vegan when people asked me. I don’t do overt active conversion, just encouragement, in the right circumstances. Again if the situation is above, there’s a balance achieved, don’t rock the boat.
For smaller monasteries, where there is only 2 or 3 monks, just make known to them that you’re a vegan. The current monastery I am staying in, Brahmavihara, I told them I am vegan, the supporters who donate food are very happy to cater to me, to have majority of the food selection offered on the table to be vegan. We’re all Chinese here so, the offerings are on a round table with a turntable. The monastery kapiya buy the food for us, or our regular volunteer cook cook for us.
Whenever we got invited outside for lunch Dana, the kapiya would inform them that at least one monk is vegan and explain the difference between vegan and vegetarian. No eggs, no milk. Just 4 simple words.
Worse case, if the donor has every dish mixed with meat, just take some of the vegetables from the dishes. Or eat plain rice. The donors would be concerned, ask why and they know next time what to do.
As for alms rounds, since I am still under dependence and living with other monks who are not vegan, I am ok with accepting meat, but just don’t eat them. Accept the meat, come back to monastery, let them arrange into buffet form, take only vegan food.
I am still gauging if it’s socially acceptable for me to put a sticker “Vegan” on my bowl. Anyway, if you’re going for alms round on your own, can just take note of few vegan restaurants, go rotate between them, today here, the next day there etc. I haven’t actually done this before.
If there’s some unavoidable meat to be taken, like Sunday market pindacara with Sasanarakkha Buddhist Sanctuary, I take a combination of the soup and noodles. Some put the meat with the noodle plastic bag, some put the meat with the soup. Not both. So I mix and match. The meat I had to take from the buffet, can just thrown into the forest and let the wild boar or cats to eat. Or throw into the pond for the fishes.
The more tricky part is for some monastery where they have the culture of offering extra food for monks who are in the middle of eating after we take our food.
Because of a vinaya rule that says if one rejects a staple food (meat falls into this), one cannot accept other food offerings.
So if you wish to have the delicious vegan ice cream which you know is coming, can just remember to accept the meat coming first, and put it aside, don’t need to eat them. Then can get the vegan food which is offered later.
The part I am still getting used to is to help take meat for other monastics who are on pindacara break. Some may just say whatever, but have an extra condition, but cannot be vegan food. So I had him specify what meat he wishes for when I help him to take, or else anything for me means I give him the same that I have. Healthy vegan selection.
I would prefer to just take total vegan food for them, but since they do cater for me, by bringing me only vegan food, I think I do owe them at least they curtosy
