Here on Earth we draw separation between us, the grass growing out of the concrete, the dog barking next door, and the borders we live within. We create barriers that help us distinguish things, ideas, and concepts. It would cause much confusion if no one knew exactly where the border of the US & Mexico precisely was. Miguel would be shouting "Amigo! Amigo! America starts 3km to the north!" While the confused border patrol officer is scratching his head.
But separation is only a partial truth. Separation serves purpose on a micro level, but it is a narrow perception of the total reality. The whole truth is we are all interconnected. We are all creations of the Earth/Universe/God or what ever you choose to believe.
My cat, Tom, died a few years ago. The next summer I was outside enjoying the electromagnetic radiation the sun provides, and I noticed a patch of grass growing almost knee high. The surrounding grass was barely pricking through my toes. My dead childhood pet was recycled by the Earth and converted into vital nutrients for my yard. It took a little while for Tom to be reincarnated, but eventually the energy of the cat was released back into the Earth.
Everything is about energy. The energy required to do the dishes is the same energy required to make a million bucks. The same energy required to warm the earth is the same energy required to make the universe tick.
We are separate, but equal. We are divided, but whole. We are infinitely large and infinitely defined. We are a piece to this strange puzzle we call life. We are energy.
