Does the Dahlia Lama suggest that we try to focus on the hated object and try to find positive things to say? Or that we try to erase them from our thoughts?
I'm certainly no Dalai Lama, but I suggest that we find the lovable part of the person and love them for it. Admittedly, it is sometimes well-hidden, but it's there in every single human. This does not imply that we encourage bad habits or praise people for the things we don't agree with, but it does imply that we understand their humanity, and that we can live with their imperfections, just as we want people to live with ours. Imo, trying to erase things from our thoughts is a practice in avoidance and denial, while trying to find positive things to say is betrayal of one's own feelings. There is no reason that we must be stirred to either extreme, when we can just let things be as they are and tend to our own lives.
