Posting reason: at the beginning of this post, is to see someone in this group sent "I enlightened, we have questions can ask", even feel flamboyant, but there are followers of faith and learning. Immediately issued this post to emulate it, marked new and different, although fear of people do not believe and denigrate, but in order to establish a realistic and empirical atmosphere, rushed to the internet generally said not practice the atmosphere, impulse to send this post. Over the course of several years, although there are troublemakers, argumentators, doubters, but there are also true practicers to post questions and feedback progress. Some people also give me feedback on the progress and harvest of the practice in bean mail. Thanks to these brothers, it makes me feel that my posting is still a little bit of value.
