Imagine you were eternal and had infinite power. You could do anything you could possibly dream of. You might start by giving yourself every pleasureable experience you can imagine. But, after a time (considering that you're infinite) this might get boring. So what do you do? You then decide to give yourself more challenging, more undesireable experiences, only so that you may get yourself out of them, renewing your experience of the pleasurable. This you can do in an infinite number of ways, in an infinite number of forms, with varying degrees of intensity, infinitely multiplying your ability to experience your immeasurable power until you have what we now call the Universe. And this you've done and will do throughout all eternity because this is simply what you are: an endlessly creative and destructive force, constantly changing forms to experience an infinite number of possibilities.
