There has never in history been a published expansive commentary on Tanna D'bei Eliyahu - the teachings of Eliyahu Hanavi. Every Motzei Shabbos for the last 17 years the Tolna Rebbe Shlita has been explaining the sefer at length, passage by passage, according to mussar and chasidus and always connected to the parsha of that week. It is UNBELIEVABLE!!!
Some time ago a sefer based on these talks was printed on B'reishis called חמין במוצאי שבת and now Devarim has come out. It is AMAZING!! [Although not as good as hearing the Rebbe Shlita in person].
Go buy it!!
