Light (and Dark too)!
"It's all about the light... and how much light and dark you have in your life... and you are lucky if you can see the light in even the darkest circumstances... it might be an illusion, or a trick of the mind, but it's a useful illusion, a useful trick... and no matter, whether you see it or not, experience it or not, it is there, or will be there... there is an endless dance of dark and light... our lives pass through this dance, we are the side-show to the flickerings... if we only see one or the other, only dark, only light, we are just being short-sighted... and we miss the intricateness of existence...
