The method of introspection must be rigorously controlled.
译文：读书学习一定要放开眼界，开阔心胸；做人一定要坚守原则和底线。赏析：读书不要死记硬背，一定要放开我们的眼界，不光要知其然，还要知其所以然。做人的底线，我们应该时刻铭记，违背社会原则的事，绝对不能做。
"That is what is so strange, that people will not believe what is really true, what is before their eyes."
For all that has been, thank you. For all that is to come, yes!
