Just as there is a language for communicating with our animals, e.g. dogs.
There must be a language for communicating with my body.
A great example is the urge to go to the bathroom, to pee.
I drive a long distance, drinking coffee.
I come to a place where there is a restroom.
My body, suddenly lets me know, it is time to go.
The door to the rest room is locked.
I try to tell my body with words, thoughts, images that this doesn't work, wait.
My body won't hear it.
Yet it does recognize that the opportunity should be there.
Communication is happening, it is just as not refined as speaking to a person.
