'Blue Light Speaks of Its Blueness' by K. Roberts

This that vibrates. This that scatters. Caresses a surface and is turned aside. When water pours, this escapes from the spout. Refuses to stay in a cup. This soaks through a body. Excites the sprites in a naked eye. Delves deeply into pores. An object can mirror. An object can sponge. The hungry sea is never full, for this floats. Blood in a wrist is not empty. This is something that loves to be held by a prism, the way sound loves the embraces of air. That can mask and unmask colors in a gemstone, but never perceives a self-reflection.  Turns anonymous when passing through space. An invisible traveler. Going everywhere, and nowhere
