This is a chassidic discourse by the Rebbe Rashab, Rabi Shalom DovBer, fifth Rebbe of Lubavitch. The subject of the discourse is the difference between the spiritual work of man when he was in Gan Eden (Paradise) and after being kicked out and sent away from there (because of his sin). The Rebbe explains the meaning of refinement of the world and the role of Bnei Noach in that refinement.
