Also called Contemplation, it requires you to do nothing and think nothing. 
It is especially helpful when you find that you simply cannot think anymore, on 
those days when you have absolutely no creativity left, when you are stressed 
out or can feel it coming. Your mind is focused on nothing in particular, but 
you have a feeling of deep peace and well-being.

In Christian terms, you rest 
in the presence of God—without the need to have any clever insights or creative 
expressions.
