Elements introduce themselves

I bet all of you've seen this very page at some point of your life. Personally I've seen it about a hundred times and still I never noticed something very essential about this page.
 

A friend of mine told me recently of his discovery:
If you look at the picture closely, there's the Heart of Kandrakar (quite obviously) then some rocks and white fire, then wind and  finally rain.
Energy, Earth, Fire, Air and Water. It's so simple and I didn't see it!!!

Thanks to Cole for making me see the importance and meaning of this page from the very first Issue of the comic in a new light.
