I searched google for images of a human brain cell being compared to images of the universe.  The similarities are astounding. The lines and patterns look almost identical. I find it extremely interesting that one small life form on one tiny planet surrounding a star, that in comparison to the rest of the celestial bodies in the universe isn’t very big, can still bare such a resemblance to the entire universe itself.  It shows you that everything in existence really is ONE. As someone who meditates often, I see these pathways through the universe as a mass transit system. Our brain seems to have its own mini transit system within itself, with all parts working together to keep us alive and provide all the functions we need to survive.
