Buddha's teaching does not resonate much with me, and I suspect that his disciples added too much of their own interpretations. The only thing I find helpful is to find the middle path (be balanced). Here are several things I find misleading/confusing from reading this book:
1. There is too much emphasize on the distinction between "good" and "bad." However, in reality, there is not always a clear cut between "good" and "bad". Your candy can be other people's poison. Who is there to judge? Also, "good" is good because there is "bad" to contrast. So why not appreciate the existence of both sides?
2. Encouraging people to do "good" deeds and despising the "bad," to follow the "good" thoughts, not the "bad" thoughts. This can certainly backfire. People will have a hard time accepting their dark side. And you will see more bad people doing good things to look good. This also contradicts yoga, where we should take notice of both good and bad thoughts, but do not judge, just be aware.
3. Too much emphasize on the suffering. The Buddhist teaching seems to like talking about selfless service a lot, and people should neglect their needs to serve others. Why not care about your needs and, if possible, also help others? Love and empathize with your ego, and you will find your ego also loves you; it just does not know how to protect you in a way that the higher wisdom does.
