Nature is at each moment in a state of becoming.
In the modern context the word nature often describes end states, the delusion that the river we might see in front of us is a permanent end state. In ancient Greek philosophy nature is in a state of coming into and going out of existence, a state of becoming, which changes one moment to the next. In the Ice Age a river ran near my house full of fish, today it is a road full of cars, the river is long gone. Evolution reflects this sense of becoming, the T-Rex dinosaurs may have chased our ancestors for lunch yesterday, but today it is often the human chasing the animal the T-Rex changed into, the chicken.
If you orientated yourself into living in a world of becoming rather than fixed states, you will live in reality rather than delusion. This new perception helps you to let go of attachments, because everything around you is temporary and changing.
Heraclitus in his cryptic observation of nature said:
17. Nature loves to hide itself.
I sat in a wood yesterday working out what Heraclitus meant, and a baby bunny rabbit appeared from the bushes, watched me a few minutes, then vanished. As nature is in a state of becoming, in any one moment the old reality is fading away, and a new reality is coming into view. In any one moment we live in a ghostly world of things fading out and coming into existence, though our brains process the moment as one end state. Reality is nature in a state of hiding, the fading away and coming into existence is like the rabbit half-hidden in the bushes. It is because of this ghostly state we exist in that we gain a sense of time, or things in motion, and it may be so that Zeno was right when he says motion as we see it may be a delusion, as he demonstrated by his paradoxes such as the Arrow.
“If everything when it occupies an equal space is at rest, and if that which is in locomotion is always occupying such a space at any moment, the flying arrow is therefore motionless.” Zeno of Elea.
