What "awe" should we have?

Having a "heart of awe" should be a way for us to restrain our behavior. We should have a bottom line in everything we do in life. We shouldn't do whatever it takes to achieve our goals. We should be in awe of morality and law. At the same time, don't be too awed, and be timid in everything. Many people may miss a lot of things because of this, and how to master proper limit is something we need to keep learning.
