Must one stand upon reciting Birchas Hatorah?
 Admur 8/3
 See Maarah Kohen 3/3; Yaskil Avdi 8/3 that this is similar to the standing of Bnei Yisrael on Har Sinai.
Other Opinions: Some Poskim rule that all Mitzvos which one fulfills sitting down may also have its blessing recited while sitting. [Peri Megadim 432 M.Z. 3; Pnei Yehoshua Megila chapter 3; Mor Uketzia 8] The Aruch Hashulchan 47/7 and Rameh 102 explicitly rule that Birchas Hatorah may be said while sitting
