There is a monk who has a crush on my mother. He is not a fake monk. He made my mother a monk. My mother really wants to become a monk. What should I do? How to save it?

The monk took a fancy to your mother, so he asked her to marry him. If he comes to persuade your mother to become a monk. I don't think it's "fancy" as you said.

If your mother is a real Buddhist practitioner, it will be great to have the idea of becoming a monk. You should wait and see for a while, and have a good talk with your mother before making a judgment. If your mother is attracted by any "monk" and wants to become a monk, her purpose may be impure. That's not a real monk, it will ruin the Buddhist atmosphere. You have to remind her. Tell her not to despise Buddhism.
