our brains neurons look exactly like the structure of the Universe

'One is only micrometers wide. The other is billions of light-years across. One shows neurons in a mouse brain. The other is a simulated image of the universe. Together they suggest the surprisingly similar patterns found in vastly different natural phenomena.'

What struck me about this is not the similarity between neuron and universe, though it's striking — 

rather it's the continuity of parallels one finds whenever one looks into the structures of nature.

"That which is Below corresponds to that which is Above, 

and that which is Above, corresponds to that which is Below, 

to accomplish the miracles of the One Thing".
