HaRav Yitzchok Sorotzkin said the following story:
The debitzener himself was present by the Second World War - r"l the holocaust:
“He was standing on the last transport going to Auschwitz. All of sudden out of nowhere, a lady appeared. This lady started screaming, ‘Jews, Jews, you know why you're suffering so much? Because you speak in the shuls during davening. This is what is causing the churban Europe.’ After she finished this, she disappeared into thin air," testified the Debitzener. It was messenger from heaven that came down and told them very clearly that the root cause of churban Europe was due to the fact that they disregarded the sanctity of their shuls in כבוד השכינה.
Does anyone know where the source for this story can be found?
