Comparison Of Harry Potter And The Philosopher's Stone

The stars are an integral part of our world, best described in the adage “As above, so below.” In a way, gazing at the heavens from the earth is like gazing into a mirror – the energy is reflected and each show qualities of the other. In the book "Harry Potter and the Philosopher 's Stone", Ronan comments on the brightness of Mars upon meeting Hagrid and the children in the Forbidden Forest. Bane, another centaur, joins Ronan moments later to make the same observation. This is significant, because the forces of violence were gaining power that very night, and Harry Potter would confront the very evil that changed his life as an infant. Firenze was the centaur who rescued Potter that night, defying custom to rush the Boy Who Lived out of the forest on his back.

Years later, in "Harry Potter and the Order of the Phoenix", Firenze speaks to Potter thus,

Mars, bringer of battle, shines brightly above us, suggesting that the fight must soon break out again. How soon, centaurs may attempt to divine by the burning of certain herbs and leaves."

Firenze, while confirming the association between Mars and battle, makes it clear that astronomy, or rather the interpreting of observations into common or precise language, is not an exact science. Everything to do with the motions of the heavenly bodies is precise, but the messages are mysterious and archetypal as opposed to plain. It is like the language of our dreams, which one could argue is most pure.
So, it would seem, astronomy has a more subtle nature than simply affecting our daily lives – though it does, in a way. It is the nature of energy, and we are beings of energy in an energetic world. All is one, so one may peek into the All by peering into the great reflecting pool above
