It is said, as above, so below. As within, so without. "...thy will be done on earth, as it is in heaven"
the basic unit of life is the cell, yet a humani is a multicellular organism. you are made of many individual cells. you are a collective: Legion in the Bible. As much as you are a single unit, you are a collective, your thoughts are yours yet, not yours alone.
what about those many voices in your head huh?
about the smallest unit of life, the cell; isnt it itself made up of organelles, those organelles made up of sub components and those subcomponents made of atom and so on and on and on??? how small do you think it goes??? Indeed, thats where life comes from. how much bigger can an organism get??? that's what infinity means: repetition in myriad different forms, the snake eating itself.
