Do you agree that your body language express emotion better than your self?

It ususally does. Professional learn how to control their body language as much as they can.

A same sentence may be said in different body language and given variable expressions.

In most cases, yes. However, my experience with different nationalities tells me that it is not always true. Another limitation of the body language is that it is interpreted in different ways by different people. As an EFL teacher worked with more than10 nationalities, I think it is not right to say100%.

Body Langauge includes Postures and Gestures That speaks more than a words. well said "Face is the  Index of heart "

Yes I agree with body  emotion but this is not every things you voice also your movement during your speech also assistance you for express any way to more professional you must to control you self specially your emotion also in other hand you must to understand who have bad experina cue in thus way cause not all are expert in this area 

I have noticed that in the Turkish serials .Actors express what they want to say without expressing it.Body language is an art.It is needed for those who speak in front of many audiences.

Yes this is true as actions speak more than words and before we speak we are judged.

Thank you.

Actually , it is better specially when it comes to a wide range of audiance .

me myself am kind of visual , I wont concetrate for only listening or talking.

For the expresion of any matter the body language is play vital role then emotion.

Yes, absolutely, the face and body will defiantly slip the actual emotions, even if the person is trying to hide them.

Some time you can read what the other want to say or their feeling from their eyes or their faces expressions , sometime you feel happiness or sadness when you look for someone before you hear and word from him .
