Sometime back, I read a very simple paraphrase of Buddha's view/thought on his enlightenment. One of the 4 things he says he achieved freedom from is opinionated views. When I read it, it made sense. However, just because something made sense does not mean it is easy to incorporate. It is difficult, very very difficult. That is the paradox of existence, you might know one thing, but end up doing another. And only you can change that, to make the paradox cease.
