We often hear the idea expressed that we are “one” with the universe and it is put forth as a spiritual reality. Thinking about it a bit brought me to the idea that we are also one with the universe in a physical sense in that we cannot exist without our physical connection to our environment.
When I think of being connected to something I think of it in terms of my existence is part and parcel of that to which I am connected. We are part of a whole. Without air I cannot exist. Without water, and moisture, and food I cannot exist. Therefore they are part of me.
Our link with the physical reality is a reflection of our spiritual connection to the universe.
