I was thinking of this just the other day. What would really embarrass and conflict me is if I were given the same name as a very prominent monk. It would make me feel very awkward, and worry that the prominent monk would feel the same way, or even resentful (even if he tried not to be), thinking I might have tried to inluence the teacher in his choice. And if I objected, even politely, I might be seen as ungrateful or troublesome. This is all pretty much academic, since I don't plan to ordain any time soon, but it's just a disturbing possibility I thought of.
