Pardon if it sounds like a naive question. But when you are in a monastery-- which sounds like a controlled environment-- I get a feeling that you are not interacting with all those grieves like rejections, loss of loved ones and other mental conflicts, struggles one goes through in this materialistic life.

Albeit they include artificial such scenarios by having a very rigid environment which is stressful and one has to learn to adapt to it.

So, practicing being calm there, I am not sure how that will translate to "the real world". Would really like to know about stories of people who practiced such things in their childhood or for a long period and how they are faring post that.
