Derech HaMelech
My point was not to question the validity of Chassidus, just to point out that we tend to accept as mesora what was in existence when we were born and question the mesorah of the new. At the time the Besht was a minority of one and went against all the gedolei hador. If the Besht had come today, you would probably be among those questioning his mesora.
BY the way one example of ” we tend to accept as mesora what was in existence when we were born and question the mesorah of the new”. Many shuls now have a hashkomah minyan on Shabbos.
But do you know its origin, its mesorah? It’s roots go back only 100 years and they were started by Jews who gave into the pressure of having to work on Shabbos but still wanted to daven with a minyan and hear the laining.
