Below is an excerpt of a letter from the director of the LaSalle-Haus describing what happened.
The retreat of Eido Shimano was not part of our program. The European Rinzai Sangha had rented our guest house and our staff was not informed about the coming of Eido Shimano.A more detailed look at the misconduct to which Karcher referred can be found on the Shimano Archive.
Being a catholic retreat centre we have very strict rules regarding misconduct.
After having been informed of Eido Shimanos coming to our center and being aware of the fact that he is a a controversial figure regarding issues of misconduct, I informed him personally, that he had to leave our center which he did a day after the sesshin had started.
