Looking deeper

This site interests me because there is so much information and it is all without advertising! I love the concept of Whole Systems - the universe is a system of systems that break down into more and more systems. The human body - a whole system, made up of the circulatory system, digestive system, musculoskeletal system...and more. The earth we live on - the atmosphere, the hydrosphere, the lithosphere. Each system a complex, intricate, interwoven set of smaller systems. Our body systems would not function without the Earth's systems. At some level, you reach unity. The Tao teaches this.
