Can I Keep My Obvious Beliefs?

If I consider only one thing important, and that is to know myself as awareness, I am told that I really need to let go of all my beliefs about life. But what about the obvious beliefs, like that my health should improve, or that humanity should be more just and humane and moral?

Even the obvious, seemingly harmless beliefs such as those have great power to capture your interest, and keep you thinking about them. You know this to be true! So be brave and let those go, too. See what happens.

When your attention goes to a thought, and away from the awareness of that thought, ask yourself, Do I need anything added to me? Is there any reason for me to pay attention to the contents of that thought if there's nothing in it that I need?
