I don't recommend doing this. Buddhist monks have dharma names, but all dharma names are given by masters, passed down from generation to generation. We lay people should never take our own dharma names casually.

What you said.

"Galo" or something is Sanskrit of ancient Tianzhu at that time, not necessarily Buddhist. As long as you know Sanskrit, you can choose your own Sanskrit name. This has little to do with Buddhism. You think it has something to do with Buddhism, mainly because Buddhism came from Tianzhu, and there are a lot of Sanskrit in the classics, and the names in the classics are also transliteration of Sanskrit.

So the relationship between Sanskrit and Buddhism is like this. So the name given can only show that it is close to Sanskrit and has little to do with Buddhist teachings.

It's best to choose a name that China people can understand. You can also refer to the teachings of Buddhism and take a Chinese name that conforms to the teachings of Buddhism. This is the real Buddhist.
