The first language our bodies ever knew was that of physical sensations and emotions. As babies we were attuned to our every need. We knew when we needed food, needing sleep, and how we needed comfort (whether it is physical touch, connection...etc). As we get older, the environment and impactful events tend to make us more disconnected from our internal body language. Emotions are just that, the language of the body. The better we learn to re-attune to this language, our own language, the more we know what our body is trying to tell us, how to best take care of ourselves, and how to relate better to others.
