This, the first of two [three] Ma’amarim that are based on a Ma’amar of the same title from ה’תרצ”ט 1939, is not normally a Shavuos title and the Rebbe addresses this anomaly. The content of the Maamar with the same title deals with Yehuda and Dovid, Torah and Ma’aseh. which are familiar themes in Chassidus. This class adds that this duality is paralleled by the Nefesh HaElokis and Nefesh HaBahamis. But the real novelty of this Maamar is that it sets up the Ma’amar to follow which is truly original.
