Reply To: Learning on Shovuos – Got It All Wrong

I really do not know what he did but in general the inyan of staying up all night is frowned upon in Yeshivos.
HaRav Shach z”l was even against the regular Thursday night mismar which is kept in many yeshivos. He would encourage yeshiva boys to learn well during the regular sedorim and to sleep well at night.
Also the Chofetz Chaim was known to turn off the lights in the Beis Midrash at night and to tell the talmidim: Tomorrow is another day. You can learn then. Now you have to sleep.”
