A friend of mine is a monk. I want to give him something. What should I give him?

I suggest you give him a chance to break his insistence. What do you think he usually insists on and gives him? Tell the layman what he wants and tell the Buddhist to help him break his obsession. Of course, you need kindness. Write a few words to remind him when you can give him something. If you maliciously want to destroy other people's practice, then you are not helping him, but helping the devil. Of course, whether you are kind or malicious, whether he can benefit from practice is his own business.
