To be or not To be with Sophrology

Why did I choose to call this ebook 'To be or not To be with Sophrology'? The only reason is that each one of us is free and unique. Unique on the earth as a human being and free to improve and take care of oneself. Sophrology is based on techniques such as concentration, deep breathing, visualisation, and simple movements. These techniques are used simply and easily in an everyday life environment.
Anyone is able to practice them from children to adults and the elderly.
