One of the main activities of Idris Laor is teaching Euphony of gestures to Samadev. To create a book from recordings of conferences and conversations, the author turned to his student and friend Jocelyn Herz with a request to help him with this. According to him, he could not have made a better choice, since Jocelyn already had successful experience in such work. In addition, she always had an interest in studying the higher nature of things. In the book you will find several notes that explain in more detail the relationship between body and spirit during the practice of Samadeva Gesture Euphony. These principles reflect the essence of most bodily practices that address the spiritual aspect.
