If you don't want to be a monk any more, are you allowed to leave?
We came here freely and stay of our own free will. This does not rule out times when it is hard to persevere. But God is faithful and his grace is in no shortage. Married couples also have a duty to be faithful to one another. On rare occasions, monks do leave. This is a great sadness for us, which we carry in our prayer. It is rather like having a living limb amputated.
