so i've been reading the book about body language by allan pease which was advised in some topic. Some what in the middle he writes about gazing and supports his theory of different gazes by pictures, so for example the power gaze would be illustrated with a picture like this.

What i dont understand is what he exactly means with the triangle, is the triangle the general area you should focus on? or should you imagine the triangle on the person you speak to and follow it?

(sorry i cant post the link or the picture because you need atleast 5 posts to do it, so please put an o instead of 0 at .c0m)
