@avaira
all his things he claims the rebbe changed, were all answered many times on this forum, actually the only thing that changed in the last 70 yrs since the rebbe became rebbe, is that being mixed with other jews, some misnagdim learned a lot of things about chassidim that he didn’t know before, and decided that they are new, just open up a keser shem tov, likutai diburim etc. (shalosh seudos? youre kidding? the alter rebbe paskened you dont need to wash even for the day seuda, his brother the maharil writes about this!)
