Hello Mikami.
It's about the monk's meal, isn't it?
Much of Japanese Buddhism is not a precepts after Denkyo Daishi reprimanded the Korahaya, so many monks other than monks who swore to keep the old 250 commandments eat the same meals as ordinary people except during ascetic practices. Rather than not eating meat, monks who are serious about their faith place emphasis on the spiritual view of eating that all meals, including meat that comes out, are eaten with gratitude without leaving anything behind.
Actually, on the contrary, this is an idea that fits the view of food during Shakyamuni's time. Actually, during the time of Buddha, people also ate meat. It was a way of life where extreme vegetarianism, such as other faiths, was not good, and since it was a beggar's ascetic practice, I ate whatever I received with gratitude. Also, since it's an illness, if you have to take nutrition, they are allowed to eat meat even according to the precepts. After the fall of the Buddha, the precepts and practices became more and more appropriate for monks' meals, denying carnivorous eating, just like other faiths.
In that sense, there is a Japanese monk's view of eating. However, traditional ascetic practices are also important, so when entering into strict ascetic practices, there are many cases where people take on the challenge by devoting themselves to the challenge.
Well, before that, there were occasional (probably quite a bit) monks who didn't value meals and drank too much (laughs). It's also my depravity as a monk, so I have to reflect on it. I want you to appreciate the meal too. Gassho
