What an interesting question- don't know the answer but wonder what brought on the question!!
I have no idea about the social conditions in those days and whether dancing at home was an activity in oriental families.
well, I think dancing at home, with wife, has not been a thing at time of Bahaullah in Iran. I cannot imagine it at all for Iran of those days, and even nowadays people do not dance together at home for no reason (or maybe they do and I am not aware!) but dancing, like romantic dancing is mostly a European thing in my view.
After all, I think He was so busy and had so many difficulties on and on and on that there was not really much time to just dance for no reason.
I can't imagine a life where there's no dancing! Dancing for no reason is a daily thing in my house! I don't think a day goes by without me dancing with my husband! Silly dancing, romantic dancing, all out dancing to loud music, it happens every day. I don't know if Bahaullah danced with his wives, it is an interesting question. I wonder what made you think of that Djg?
I hope he did, never dancing with ones spouse would be a bit sad. But maybe he was too preoccupied for that, or it wasn't culturally normal, who knows!
