Into eternity! (well, that may be a bit exagerated).
I find the concept of proportion fascinating. It's the human way of adapting everything to our level of perception. One might say a cat is small, yet the same cat is large in comparison to an ant, pretty much in the same way our planet is humongous, but minuscule when compared to the vast and trackless expanse of our infinite universe.
And speaking of universe...
The mind is an oxymoron in that it is infinite as the universe, but in turn quite limited. Our thoughts and perception are limited to that which we see, so simply imagining the distance between Earth and Mars is a difficult task. We may know the number of kilometers from here to la Planète Rouge, but it is hard, if not impossible to envision it. The study of physics requires a fair amount of abstraction that few are able to achieve.
Also on the topic of the mind, there is a song I'm particularly fond of, Equilibrium (by Tristania).
A part of the lyrics go like this:
I swim in you
In your dark rivers
Dive in your mind
Search for your monsters
Search for resistance
Sink into the mud
Dance in the halls of insanity
Yet madness is
Your highest deed
Lovely, is it not? O have I not danced those halls before, taking vain pride on my senseless dance.
On that note, dear readers, it is time for me to withdraw from this side of our magnificent global network. Please, do comment. I promise to write more often.
