Class One. The answer to the question about serving Hashem with אמת. The Rebbe explains the idea of joining רעותא דליבא with one’s שכל ומדות.
Class Two. This class discusses the two ideas: 1) The lower level of the Neshama is אלקות שנעשה נברא. Though it is Godly it is much lower than Godliness and certainly lower than Godliness on the highest levels. 2) The two levels of the Neshama are compared to two levels in מראה- how Godliness expresses Hashem. One level says nothing beyond חכמת אדם תאר פניו. The second is like the light that fills space and illuminates the darkness. The first is higher, the second is lower. They represent the two levels of the Neshama: the higher and lower levels.
Class Three. In Torah these two levels also exist: Black fire on white fire: Light that illuminates darkness and light that is absolute. From Torah it comes to the world: Sovev and Mimalei (Kav).
