“The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself.” – Carl Sagan
A neuron in the brain is juxtaposed with clusters of galaxies and their filaments are connected of matter and dark matter. The resemblance is clear. The implication? You may have an entire universe in your head.
The human brain is literally one of the most complex structures known in the Universe, which is itself the greatest of all complexity. Your brain has billions neurons. Neurons are also networked, communicating to each other. There are trillion connections between neurons forming the neural network that creates who you are.
Our bodies are literally made of stars. We are made of the ashes of the stars. A whole universe of connections is in your mind (a universe within a universe) and one capable of reaching out to the other that gave rise to it. Billions of neurons touching billions of stars, surely spiritual.
We are made of atoms forged in the stars.
