Rav Yirmiyahu Kaganoff shlita, a poseik in Eretz Yisroel, has recently written some interesting words about a not so well known Polish gadol who lived in Baltimore, R. Michoel Forshlager z"l, in two installments.
In the second part, the following is stated
"in Sochatchov they did not allow the bachurei yeshivah to attend the tishin of the rebbe, since this would take away from their single-minded goal of growing in learning."
Sochatchov, a leading, and influential Polish Chasidic dynasty, was known for placing great emphasis on limud haTorah.
This is in contrast to what I heard a while ago from Rabbi Moshe Weinberger, mashpia at Yeshiva University, and Rabbi of Cong. Aish Kodesh in NY, in one of his lectures. He said there, in a talk about the Chasidic Shabbos, that as opposed to what outsiders might think, by Chasidim there was no thought that attending a tish could be a problem of bittul Torah (you can hear it here, at app. 18:50). Obviously, that was not correct. At least not in Sochatchov. And I suspect that Sochatchov was not the only place with such a position.
Moral of the story - caveat emptor - buyer beware. Be a critical consumer. Not everything that is stated out there is accurate.
P.S. I read a while ago of a similar thing in another Chasidus in the past as well (Sanzer?).
