Our physical body is composed of a multitude of cells

"Our physical body is composed of a multitude of cells, and each
of these cells is a living entity, a minute intelligent soul that
knows how to breathe, take in food and eliminate. Look at how the
cells of the stomach, liver, sexual organs, heart or brain work -
each one is a specialist. And this intelligence is simply the sum
of the intelligences of all these little living beings. We are
dependent on them and they on us - we are one.
Human beings can do nothing without the consent of their cells.
The moment their cells stop working, stop contributing to the
efficient running of their body, they are no longer able to
breathe, to be nourished, to move or think. And protesting won't
make any difference. So they have to understand that they are the
synthesis of all these minute intelligent souls within, and that
they have to take good care of them every day."
