Body Language is the language which our bodies speak, many times even without our conscious knowledge. But, when we speak, our body language must be in congruence with our oral words. People tend to believe our body language more than what we speak, whenever there is any variance between the two. Body language is a truth teller. We must improve our body language if we want to be a more effective communicator. Observing other's body language also helps us to understand what others want to actually convey. So, closely observing body language can greatly improve our interpersonal skills, and help us to maintain cordial relationship with every body.
