Class One. One must engage in the war of birurim, and go out with a winning attitude, and then Hashem gives us victory. The victory is also ours and we elevate sparks taking back what was K’dusha in the first place. After the basic Birur and elevation we must refine it, even to the extent of cutting hair and nails until it can become K’dusha itself like a marriage.
Class Two. Second class on the Ma’amar, how this relates to us. Avoda and Milchama are Tefilla (Davening). This war is especially about Reshus which includes (both) the advantage of an action (in the case of the seven Mitzvos DiRabanan) and the higher light of Lo Ta’ase.
