From time to time I search the web and I came across a tribute in his name

by Eva Laser

"Dear all, 

Below is a link to a tribute to Yochanan Rywerant, born in Czernowitz 
in the 1920's, deported to Transnistria with his mother Shulamit 
Wurmbrand in 1941, survived in Mogilev working at Jagendorf's Foundry, 
studied, worked and taught with Dr. Moshe Feldenkrais for many decades 
in Israel, taught the Feldenkrais method throughout the world, and 
wrote a number of books about it.

Yochanan was a first cousin of my father's. May he rest in peace. 

Marianne ”

I continued to search the web and found a book ”Ghosts of Home: The Afterlife of Czernowitz by Marianne Hirsch and Leo Spitzer” . In 14/12-20 I find this link Link[+]

After I have read this book, I have understood in depth the distinctive ethical approach that characterized Yochanan's teaching and metateaching FI. His excellence in differentiating acceptance from tolerance and making it clear to every student that is was not self understood that we, as teachers, had the right to touch someone else. He made it clear that every single touch or manipulon was information to the Other and needed to be understood and processed. And we should not be careless how we delivered that information. Over the years I have communicated with many teachers who studied with him and I find that this is a message that he delivered and made alive. Something that could be seen as technique but with the years appears to be something completely else. And as it is in the domain of non-verbal communication it is not possible to catch it in some lines like this. It is to be found in the elusive but when present very obvious.
