"... אפילו כל ה"אונגארישע ספרים

I don't usually like to post such clippings, simply because it seems like we have something to prove. But the "Ungarishe Seforim" line is what grabbed my attention. Ungarishe Seforim are basically scorned upon by their Polish and Russian counterparts. The Litvaks goes without saying. Other than the Chasam Sofer and a few others, of course. Most Geonim wouldn't bother with the Ungarishe Seforim, it's a waste of their time. But the Rebbe knew that תורה היא וללמוד אני צריך. There is a story of a Jew who met the Rebbe in Yechidus and was asked where he learned in Europe. The man foolishly dismissed the question, telling the Rebbe, איר האט מסתמא נישט געהערט פון אים, his name was Reb Shimon Greenfeld of Semihaly. To which the Rebbe responded, MaHarSHaG? He brings the Alter Rebbe in his Tshuvos some 77 times!
