When we split the order of reality, and place "spiritual" things here, and "physical" things there, we do an injustice to both.  Different frequencies of light are simply that.  The palette of realty includes all colors, in every shade, without limit.  When you brighten someone's day, you literally do just that, with your very being.  You enlighten day and night, and your whole world shimmers with you.  The less you hide, the more you shine.
