Relaxing and improved use of my left side

It is easy to tell people to relax but often difficult for people to achieve. With myself I am finding that the left side is not the same as the right side. There is an asymmetry and not being aware of the difference feels to me to contribute to the problem. It feels to be an illusion that I am of one mind. As I play with the left tongue the more relaxed I feel overall. It seems to be tied to improved use of the tongue.
