"Organs. Little bits of the outside captured inside the physical body.
Like when the developing embryo forms an invagitation, then rolls in a bit of the outside skin. That first capture becomes the neural tube, the beginnings of the nervous system. From that grows all the sensory organs and brain -- that which has the ability to reflect the outer world because it starts by capturing a bit of it. The organs develop as astral centers, internalizing some of the outside -- while for plants, all that astral stuff stays outside. Then because the animal has it's own astral centers, it can be mobile."
Dude! that is a beautiful image. Thank you.
