Every single atom is doing its thing, which is perfect, and brings into being the next moment without any interference from us. Everything is perfect on the level that everything is made of atoms. Everything is exactly as it should be. Everything is perfect—the end of making or the making of the end. The end is always now. The making is always now. Now is always perfect.
We are but grains of sand
falling through the hour glass
in God's hand.
If we assume there is a purpose to nature, then nature will be evolving towards its purpose. Whatever our individual nature is, following it will be part of nature's purpose, and whatever mankind's nature is will be the purpose of mankind. By following our nature, we will be following nature's purpose.
Our very first natural action is to be inquisitive. To enquire is our purpose. We are here to know. We don't need to know where we flow, but the reason for our flow is to know.
The greatest achievement that a man can make, is to understand himself. Be able to conceive what he is and where, who he is and how and ultimately, why. To know how to steer his ship, and where to steer it to.
