This is connected to another phenomenon in the Charedi world. It has the characteristics of the Eastern cults. Every small Charedi groups seems to have it s own Guru that they attribute Divine powers to.
I am willing to admit that every city should have a a class in the Talmud in the local Beit Midrash. I have been an advocate of Beit Midrash Judaism for a long time. That is every city should have a place for Jews to get together an learn Torah- but not for money.
I have been doing plenty of thinking about cults and sadly I have way too much experience with them.
But most of the time I look at them from a mystical point of view. I try to understand if their powers are true at all and if they are they are they from the Side of Good or the Dark Side? Recently I have been looking at this question from the standpoint of Sociology. After all in spite of my distance for the profession I admit that Max Weber and the originators of the profession has good insights.
