Nature is like a canvas, a painting of countless options and possibilities. You don't really worship spirit, because you are also spirit, and spirits don't worship one another. What makes you different from spirit overall is that you are locked into temporality. You have a body, like a piece of cloth that is decayable. While you stay in it, it's hard for you to have the same abilities that spirit has without a body. It is also easy to make mistakes about what is real, and how to go about things effectively.
