Natural Cycles

I find this cycle quite confrontational. When talking about the aspect of nature, is it the aspect that it is full of lessons to be learned or is it the aspect of cycles? I find the truth to be revealing, because our lives are centered around nature. Mother nature presents us, our properties, facts, etc, in many different forms since we're related to other organisms as well as the fact that we're not the only thing that's alive on this planet. We share many things, many similarities between other creatures but since we have developed so far, strayed so far away from mother nature, we still possess some sort of uniqueness about us (human beings). The aspect of cycles in nature is one that is not new, simply, everything is in a cycle. I believe the most natural shape is probably a circle, (in my opinion... but who's to say and dictate what is the most natural shape and who would be the arbitrator of this decision? but I'll present my reasons... it's the only shape without any corners or anything and the distance from one point to the next is the same and at the same angle, and so many other properties I'm too lazy to name) and a cycle is like a circle. Like in Lion King, the song, The Circle of Life really gives this aspect of nature a true definition. Other things happen in cycles, such as rain, the winds, the earth around the sun, etc etc etc.
