If you are feeling a little down, then please look up. Do you see that the sky is also blue? Most likely, you are blue for the same reason that the sky is blue.
Once upon the 19th century, a British lord discovered why the sky is blue. Because he was also a physicist, people believed him. Our atmosphere, he explained, has lots of stuff floating in it. When the sun’s light tries to get through, these molecules scatter the light, especially the blue light, which is on the short side.
So that’s what you see when you look at the sky. The scattered blue light. Factually, the sky isn’t really blue. It only appears that way because of scattered light.
Take heart. You are not really blue. You just feel that way because of how scattered your thinking is.
So get rid of the thoughts that scatter you blue.
