When a monk came to say good bye to Chao-chou Tsung-shen (778-897), a brilliant Chinese Ch'an master.
-Where will you go?
The monk answered:
-Any place where I can learn Buddha dharma.
You keep saying about it and limiting it with your categories but reality isn't constrained by your concept of nonverbals either. So, you can say what you like and want to about it. What do you want to say about it? Are you slouching, hunched, or sitting up straight? Is your body language paying attention? Will it answer you back? Yes, listen and it does dodah.
